IS31AP2005 - 2.95W MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER

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 component count, system cost, and simplifying design. Operating in a single 5V supply, IS31AP2005 is capable of driving 4Ω speaker .
