a Filter mm mm MicroStar Junior BGA and TSSOP Package Options W Into a Ω Speaker (THD+N <1%) <0.2% THD+N at 1.5 kHz, Into a Ω Load Extremely Efficient Third Generation 5-V Class-D Technology: Low-Supply Current (No Filter): mA Low-Supply Current (Filter): 7.5 mA Low-Shutdown Current: 0.05 µ A Low-Noise Floor: µ V RMS (No-Weighting Filter) Maximum Efficiency Into Ω Internal Gain Settings: to 23.5 dB PSRR: -77 dB Integrated Depop Circuitry Short-Circuit Protection (Short to Battery, Ground, and Load) High-Efficiency For Extended Battery Run Time The TPA2000D1 is a 2-W mono bridge-tied-load (BTL) class-D amplifier designed to drive a speaker with at least Ω impedance. The amplifier uses TI's third generation modulation technique, which results in improved efficiency and SNR. It also allows the device to be connected directly to the speaker without the use of the LC output filter commonly associated with class-D amplifiers (this results in EMI that must be shielded at the system level). These time. The gain of the amplifier is controlled by two input terminals, GAIN1 and GAIN0. This allows the amplifier to be configured for a gain of 12, 18, and 23.5 dB. The differential input terminals are high-impedance CMOS inputs, and can be used as summing nodes. The class-D BTL amplifier includes depop circuitry to reduce the amount of turnon pop at power up and when cycling SHUTDOWN The TPA2000D1 is available in the 16-pin TSSOP and MicroStar Junior BGA packages that drive W of continuous output power into a Ω load.

www.ti.com APPLICATION INFORMATION ELIMINATING THE OUTPUT FILTER WITH THE TPA2000D1 EFFECT ON AUDIO TRADITIONAL CLASS-D MODULATION SCHEME O V ±5 V +5 V Current OUTP Differential Voltage Across Load OUTN TPA2000D1 MODULATION SCHEME TPA2000D1 SLOS328F JUNE 2000 REVISED MARCH 2004 This section explains why the user can eliminate the output filter with the TPA2000D1. The class-D amplifier outputs a pulse-width modulated (PWM) square wave, which is the sum of the switching waveform and the amplified input audio signal. The human ear acts as a band-pass filter such that only the frequencies between approximately Hz and kHz are passed. The switching frequency components are much greater than kHz, so the only signal heard is the amplified input audio signal. The traditional class-D modulation scheme, which is used in the TPA005Dxx family, has a differential output where each output is 180 degrees out of phase and changes from ground to the supply voltage, V DD Therefore, the differential prefiltered output varies between positive and negative V DD where filtered 50% duty cycle yields V across the load. The traditional class-D modulation scheme with voltage and current waveforms is shown in Figure Even at an average of V across the load (50% duty cycle), the current to the load is high, causing high loss, and a high supply current. Figure Traditional Class-D Modulation Scheme Output Voltage and Current Waveforms Into an Inductive Load With No Input The TPA2000D1 uses a modulation scheme that still has each output switching from to the supply voltage. However, OUTP and OUTN are now in phase with each other with no input. The duty cycle of OUTP is greater than 50% and OUTN is less than 50% for positive voltages. The duty cycle of OUTP is less than 50% and OUTN is greater than 50% for negative voltages. The voltage across the load sits at V throughout most of the switching period greatly reducing the switching current, which reduces any I R losses in the load.

The TPA2000D1 Output Voltage and Current Waveforms Into an Inductive Load SCHEME The main reason that the traditional class-D amplifier needs an output filter is that the switching waveform results in maximum current flow. This causes more loss in the load, which causes lower efficiency. The ripple current is large for the traditional modulation scheme because the ripple current is proportional to voltage multiplied by the time at that voltage. The differential voltage swing is V DD and the time at each voltage is half the period for the traditional modulation scheme. An ideal LC filter is needed to store the ripple current from each half cycle for the next half cycle, while any resistance causes power dissipation. The speaker is both resistive and reactive, whereas an LC filter is almost purely reactive. The TPA2000D1 modulation scheme has little loss in the load without a filter because the pulses are short and the change in voltage is V DD instead of V DD As the output power increases, the pulses widen making the ripple current larger. Ripple current could be filtered with an LC filter for increased efficiency, but for most needed. An LC filter with a cutoff frequency less than the class-D switching frequency allows the switching current to flow through the filter instead of the load. The filter has less resistance than the speaker that results in less power dissipated, which increases efficiency.

If the amplitude of the waveform is high enough and the frequency of the square wave is within the bandwidth of the speaker, the square wave could cause the voice coil to jump out of the air gap and/or scar the voice coil. A 250-kHz switching frequency, however, is not significant because the speaker cone movement is proportional to 1/f for frequencies beyond the audio band. Therefore, the amount of cone movement at the switching frequency is very small. However, damage could occur to the speaker if the voice coil is not designed to handle the additional power. To size the speaker for added power, the ripple current dissipated in the load needs to be calculated by subtracting the theoretical supplied power SUP THEORETICAL from the actual supply power SUP at maximum output power OUT The switching power dissipated in the speaker is the inverse of the measured efficiency η MEASURED minus the theoretical efficiency η THEORETICAL all multiplied by P OUT The maximum efficiency of the TPA2000D1 with an Ω load is 85%. Using Equation with the efficiency at maximum power (78%), we see that there is an additional 106 mW dissipated in the speaker. The added power dissipated in the speaker is not an issue as long as it is taken into account when choosing the speaker. Design the TPA2000D1 without the filter if the traces from amplifier to speaker are short. The TPA2000D1 passed FCC and CE radiated emissions with no shielding with speaker wires eight inches long or less. Notebook PCs and powered speakers where the speaker is in the same enclosure as the amplifier are good a filter. A ferrite bead filter (shown in Figure can often be used if the design is failing radiated emissions without a filter, and the frequency sensitive circuit is greater than MHz. This is good for circuits that just have to pass FCC and CE because FCC and CE only test radiated emissions greater than MHz. If choosing a ferrite bead, choose one with high impedance at high frequencies, but low impedance at low frequencies. Use an LC output filter if there are low frequency MHz) EMI sensitive circuits and/or there are long leads from amplifier to speaker.

(4) TPA2000D1 SLOS328F JUNE 2000 REVISED MARCH 2004 APPLICATION INFORMATION (continued) The gain of the TPA2000D1 is set by two input terminals, GAIN0 and GAIN1. The gains listed in Table are realized by changing the taps on the input resistors inside the amplifier. This causes the input impedance i to be dependent on the gain setting. The actual gain settings are controlled by ratios of resistors, so the actual gain distribution from part-to-part is quite good. However, the input impedance can shift by up to 30% due to shifts in the actual resistance of the input resistors. For design purposes, the input network (discussed in the next section) should be designed assuming an input impedance of k Ω which is the absolute minimum input impedance of the TPA2000D1. At the higher gain settings, the input impedance can increase as high as 115 k Ω Table GAIN SETTINGS AMPLIFIER GAIN INPUT IMPEDANCE (dB) Ω GAIN1 GAIN0 TYP TYP 104 23.5 Each gain setting is achieved by varying the input resistance of the amplifier, which can range from its smallest value to over six times that value. As a result, if a single capacitor is used in the input high-pass filter, the dB or cutoff frequency also changes by over six times. The -3-dB frequency can be calculated using Equation

In this case, C i and the input impedance of the amplifier i form a high-pass filter with the corner frequency determined in Equation The value of C i is important because it directly affects the bass (low frequency) performance of the circuit. Consider the example where Z i is k Ω and the specification calls for a flat bass response down to Hz. Equation is reconfigured as Equation In this example, C i is 0.1 µ so one would likely choose a value in the range of 0.1 µ F to µ If the gain is known and constant, use Z i from Table to calculate C i A further consideration for this capacitor is the leakage path from the input source through the input network i and the feedback network to the load. This leakage current creates a dc offset voltage at the input to the amplifier that reduces useful headroom, especially in high gain applications. For this reason, a low-leakage tantalum or ceramic capacitor is the best choice. When polarized capacitors are used, the positive side of the capacitor should face the amplifier input in most V DD /2, which is likely higher than the source dc level. It is important to confirm the capacitor polarity in the application. C i must be times smaller than the bypass capacitor to reduce clicking and popping noise from power on/off and entering and leaving shutdown. After sizing C i for a given cutoff frequency, size the bypass capacitor to times that of the input capacitor. The TPA2000D1 is a high-performance CMOS audio amplifier that requires adequate power supply decoupling to ensure the output total harmonic distortion (THD) is as low as possible. Power supply decoupling also prevents oscillations for long lead lengths between the amplifier and the speaker. The optimum decoupling is achieved by using two capacitors of different types that target different types of noise on the power supply leads. For higher frequency transients, spikes, or digital hash on the line, a good low equivalent-series-resistance (ESR) ceramic capacitor, typically 0.1 µ F placed as close as possible to the device V DD lead works best. For filtering lower-frequency noise signals, a larger aluminum electrolytic capacitor of µ F or greater placed near the audio power amplifier is recommended. The midrail bypass capacitor BYP is the most critical capacitor and serves several important functions. During start-up or recovery from shutdown mode, C BYP determines the rate at which the amplifier starts up. The second function is to reduce noise produced by the power supply caused by coupling into the output drive signal. This noise is from the midrail generation circuit internal to the amplifier, which appears as degraded PSRR and THD+N. Bypass capacitor BYP values of 0.47- µ F to µ F ceramic or tantalum low-ESR capacitors are recommended for the best THD and noise performance.

www.ti.com CBYP 10 Ci (8) DIFFERENTIAL INPUT SHUTDOWN MODES USING LOW-ESR CAPACITORS TPA2000D1 SLOS328F JUNE 2000 REVISED MARCH 2004 Increasing the bypass capacitor reduces clicking and popping noise from power on/off and entering and leaving shutdown. To have minimal pop, C BYP should be times larger than C i The differential input stage of the amplifier cancels any noise that appears on both input lines of the channel. To use the TPA2000D1 EVM with a differential source, connect the positive lead of the audio source to the INP input and the negative lead from the audio source to the INN input. To use the TPA2000D1 with a single-ended source, ac ground the INN input through a capacitor and apply the audio single to the input. In a single-ended input application, the INN input should be ac-grounded at the audio source instead of at the device input for best noise performance. The TPA2000D1 employs a shutdown mode of operation designed to reduce supply current DD to the absolute minimum level during periods of nonuse for battery-power conservation. The SHUTDOWN input terminal should be held high during normal operation when the amplifier is in use. Pulling SHUTDOWN low causes the outputs to mute and the amplifier to enter a low-current state, I DD(SD) µ SHUTDOWN should never be left unconnected because amplifier operation would be unpredictable. Low-ESR capacitors are recommended throughout this application section. A real (as opposed to ideal) capacitor can be modeled simply as a resistor in series with an ideal capacitor. The voltage drop across this resistor minimizes the beneficial effects of the capacitor in the circuit. The lower the equivalent value of this resistance, the more the real capacitor behaves like an ideal capacitor.

This frequency represents the optimization of audio fidelity due to oversampling and the maximization of efficiency by minimizing the switching losses of the amplifier. The recommended values are a resistance of 120 k Ω and a capacitance of 220 pF. Using these component values, the amplifier operates properly by using tolerance resistors and 10% tolerance capacitors. The tolerance of the components can be changed as long as the switching frequency remains between 200 kHz and 300 kHz. Within this range, the internal circuitry of the device provides stable operation.

The pops occur because the common-mode input range is worse at the lower supply voltages. At low supply voltages, the inputs are not within the common-mode input range when coming out of shutdown. The outputs develop an offset voltage until the inputs settle within the common-mode input range. This causes a pop. Figure shows 1-M Ω resistors added to form voltage dividers. The voltage dividers bias the inputs to V DD that keeps the pop low at turn on and when coming out of shutdown. The resistors should be tolerance to ensure the offset voltage is not increased.
