Datasheet Summary
3W@5.0V MONO FILTER-LESS, CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION The IS31AP2010B is a high efficiency, 3W@5.0V mono filter-less class-D audio power amplifier. A low noise, filter-less PWM architecture eliminates the output filter, reduces external ponent 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 pared to a typical class- AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer speaker can each be driven by the IS31AP2010B. The gain of IS31AP2010B is...
