Datasheet Summary
2.95W MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION The IS31AP2005 is a high efficiency, 2.95W mono class-D audio power amplifier. A low noise, filter-less PWM architecture eliminates the output filter, reducing external ponent count, system cost, and simplifying design. Operating in a single 5V supply, IS31AP2005 is capable of driving 4Ω speaker load at a continuous average output of 2.95W with 10% THD+N. The IS31AP2005 has high efficiency with speaker load pared to a typical class AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the IS31AP2005. The gain of IS31AP2005 is externally configurable...
