... A low noise, filter-less PWM architecture eliminates the output filter, reduces external component count, system cost, and simplifying design. Operating in a single 5.0V supply, IS31AP2010B is capable of driving 4Ω speaker load at a continuous average output of 3W@10% THD+N. The IS31AP2010B has high efficiency with speaker load compared to a typical class- AB amplifier ...

... Place the input resistors very close to the IS31AP2010B to limit noise injection on the high-impedance nodes. For optimal performance the gain should be set to 2V/V or lower. Lower gain allows the IS31AP2010B to operate at its best, and keeps a high voltage at the input making the inputs less susceptible to noise. Decoupling Capacitor (C ...

Resistor are needed on the IN - terminal to match the P impedance on the IN+ terminal. The single-ended inputs must be driven by low impedance sources even if one of the inputs is not outputting an ac signal ...
