The top drawing in Figure illustrates the conventional Line Driver amplifier connection to the load and output signal. DC blocking capacitors are often large in value. The line load (typical resistive values of 600 Ω to k 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. Figure 13. 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. The bottom block diagram and waveform of Figure illustrate the ground-referenced Line Driver architecture. This is the architecture of the DRV600. DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the DRV600. These capacitors block the DC portion of the audio source and allow the DRV600 inputs to be properly biased to provide maximum performance. These capacitors form a high-pass filter with the input impedance of the DRV600. 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 DRV600. Because the gain of the DRV600 is 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. TOTAL HARMONIC DISTORTION NOISE vs OUTPUT VOLTAGE Figure 14. The DRV600 is a DirectPath Line Driver amplifier 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 DRV600 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 DRV600 have a built-in charge pump which serves to generate a negative rail for the line driver. Because the line driver 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 DRV600 can shut down in an overvoltage protection mode to prevent damage to the device. The DRV600 resume normal operation once the supply is reduced to 4.5 V or lower. The exposed metal pad on the DRV600RTJ package 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. The SGND and PGND pins of the DRV600 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.
