The IS31AP2145A is a 2.9W @ 5.0V mono, clip-less, filter-less, high efficiency Class-D audio power amplifier with automatic gain control.
The IS31AP2145A integrates an 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 IS31AP2145A also provides thermal and over current protection functions.
The demo board has four modes (AGC1, AGC2, AGC OFF, and SHUTDOWN) to test the functionality of the IS31AP2145A.
