The TPA4411 and TPA4411M are ideal for small portable electronics where size and cost are Notebook Computers critical design parameters. CD MP3 Players The TPA4411 and TPA4411M are capable of driving Smart Phones mW into a 16- Ω load at 4.5 Both TPA4411 and Cellular Phones TPA4411M have a fixed gain of 1.5 V/V and PDAs headphone outputs that have 8-kV IEC ESD protection. The TPA4411 and TPA4411M have independent shutdown control for the right and left audio channels. The TPA4411 is available in a 2.18 mm 2.18 mm WCSP and mm mm Thin QFN packages. The TPA4411M is available in a mm mm Thin QFN package. The TPA4411RTJ package is a thermally optimized PowerPAD package allowing the maximum amount of thermal dissipation and the TPA4411MRTJ is a thermally enhanced PowerPAD package designed to match competitive package footprints.

(2) TPA4411 TPA4411M SLOS430E AUGUST 2004 REVISED MARCH 2008 Single-supply headphone amplifiers typically require dc-blocking capacitors. The capacitors are required because most headphone amplifiers have a dc bias on the outputs pin. If the dc bias is not removed, the output signal is severely clipped, and large amounts of dc current rush through the headphones, potentially damaging them. The top drawing in Figure illustrates the conventional headphone amplifier connection to the headphone jack and output signal. DC blocking capacitors are often large in value. The headphone speakers (typical resistive values of Ω or Ω combine with the dc blocking capacitors to form a high-pass filter. Equation shows the relationship between the load impedance L the capacitor O and the cutoff frequency C C O can be determined using Equation where the load impedance and the cutoff frequency are known. If f C is low, the capacitor must then have a large value because the load resistance is small. Large capacitance values require large package sizes. Large package sizes consume PCB area, stand high above the PCB, increase cost of assembly, and can reduce the fidelity of the audio output signal. Two different headphone amplifier capacitors. The Capless amplifier architecture is implemented in the same manner as the conventional amplifier with the exception of the headphone jack shield pin. This amplifier provides a reference voltage, which is connected to the headphone jack shield pin. This is the voltage on which the audio output signals are centered. This voltage reference is half of the amplifier power supply to allow symmetrical swing of the output voltages. Do not connect the shield to any GND reference or large currents will result. The scenario can happen if, for example, an accessory other than a floating GND headphone is plugged into the headphone connector.

Amplifier a single supply but makes use of an internal charge pump to provide a negative voltage rail. Combining the user provided positive rail and the negative rail generated by the IC, the device operates in what is effectively a split supply mode. The output voltages are now centered at zero volts with the capability to swing to the positive rail or negative rail. The DirectPath amplifier requires no output dc blocking capacitors, and does not place any voltage on the sleeve. The bottom block diagram and waveform of Figure illustrate the ground-referenced headphone architecture. This is the architecture of the TPA4411. DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the TPA4411 and TPA4411M. These capacitors block the DC portion of the audio source and allow the TPA4411 and TPA4411M inputs to be properly biased to provide maximum performance. These capacitors form a high-pass filter with the input impedance of the TPA4411 and TPA4411M. The cutoff frequency is calculated using Equation For this calculation, the capacitance used is the input-blocking capacitor and the resistance is the input impedance of the TPA4411 or TPA4411M. Because the gains of both the TPA4411 and TPA4411M are fixed, the input impedance remains a constant value. Using the input impedance value from the operating characteristics table, the frequency and/or capacitance can be determined when one of the two values are given.

The PVSS capacitor must be at least equal to the charge pump capacitor in order to allow maximum charge transfer. Low ESR capacitors are an ideal selection, and a value of 2.2 µ F is typical. Capacitor values that are smaller than 2.2 µ F can be used, but the maximum output power is reduced and the device may not operate to specifications.

Figure 75. The TPA4411 and TPA4411M are DirectPath headphone amplifiers that require adequate power supply decoupling to ensure that the noise and total harmonic distortion (THD) are low. A good low equivalent-series-resistance (ESR) ceramic capacitor, typically 2.2 µ placed as close as possible to the device V DD lead works best. Placing this decoupling capacitor close to the TPA4411 or TPA4411M is important for the performance of the amplifier. For filtering lower frequency noise signals, a 10- µ F or greater capacitor placed near the audio power amplifier would also help, but it is not required in most device. The TPA4411 and TPA4411M have a built-in charge pump which serves to generate a negative rail for the headphone amplifier. Because the headphone amplifier operates from a positive voltage and negative voltage supply, circuitry has been implemented to protect the devices in the amplifier from an overvoltage condition. Once the supply is above 4.5 the TPA4411 and TPA4411M can shut down in an overvoltage protection mode to prevent damage to the device. The TPA4411 and TPA4411M resume normal operation once the supply is reduced to 4.5 V or lower. The exposed metal pad on the TPA4411RTJ and TPA4411MRTJ packages must be soldered down to a pad on the PCB in order to maintain reliability. The pad on the PCB should be allowed to float and not be connected to ground or power Connecting this pad to power or ground prevents the device from working properly because it is connected internally to PVSS. Both the TPA4411 and TPA4411M are available in a mm 4mm QFN. The exposed pad on the bottom of the package is sized differently between the two devices. The TPA4411RTJ PowerPAD is larger than the TPA4411MRTJ PowerPAD. Please see the layout and mechanical drawings at the end of the datasheet for proper sizing. The SGND and PGND pins of the TPA4411 and TPA4411M must be routed separately back to the decoupling capacitor in order to provide proper device operation. If the SGND and PGND pins are connected directly to each other, the part functions without risk of failure, but the noise and THD performance do not meet the specifications.
