Additional preview pages of the ft2145B datasheet.

The ft2145B is a high-efficiency, filterless Class-D audio power amplifier with automatic level control (ALC).

ALC on the audio output signals, which detects the output clipping caused by the over-level input signal and automatically adjusts the voltage gain of the amplifier to eliminate the clipping while maintaining the maximally-allowed dynamic range of the audio output signals. The ALC also eliminates the output clipping due to low battery supply voltage. As a Class-D power amplifier, the ft2145B features high efficiency (up to 90%) and high PSRR (75dB at 217Hz), which make the device an ideal audio.
