Overview

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 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. In cellular handsets, the earpiece, speaker phone, and melody ringer speaker can each be driven by the IS31AP2010B. The gain of IS31AP2010B is externally configurable which allows independent gain control from multiple sources by summing signals from each function. IS31AP2010B is available in UTQFN-9 packages. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
