概觀

The IS31AP2145E is a [email protected] mono, clip-less, filter-less, high efficiency Class-D audio power amplifier with automatic gain control. The IS31AP2145E 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 IS31AP2145E also provides thermal and over current protection functions. In addition to these features, 90% high efficiency, improved RF-rectification immunity, a fast start-up time and small package size make IS31AP2145E ideal choice for cellular handsets, PDAs and other portable applications. IS31AP2145E is available in a 1.5mm×1.5mm UTQFN-9 package.
