概觀

The IS31AP2006 is a high efficiency, 3W mono Class-D audio power amplifier. A low noise, filter-less PWM architecture eliminates the output filter, reducing external component count, system cost, and simplifying design. Operating in a single 5V supply, IS31AP2006 is capable of driving 4Ω speaker load at a continuous average output of 3W with 10% THD+N. The IS31AP2006 has high efficiency with speaker load compared to a typical Class-AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the IS31AP2006. The gain of IS31AP2006 is externally configurable which allows independent gain control from multiple sources by summing signals from each function. The IS31AP2006 is available in DFN-8 (3mm×3mm) package.
