IS31AP2145B 2.7W@5.0V MONO CLIP-LESS & FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER Preliminary Information May 2012 GENERAL DESCRIPTION The IS31AP2145B is a 2.7W@5.0V mono, clip-less, filter-less, high efficiency Class-D audio power amplifier with automatic gain control. The IS31AP2145B integrates AGC (Automatic Gain Control) function to automatically prevent distortion of the audio signal by which we can enhance audio quality and also protect the speaker from damage at high power levels. The AGC function and its attack time/release time are selectable via the CTRL pin. The IS31AP2145B also provides thermal and over current protection functions.
