| Features |
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 solution for portable devices that are powered by a single-cell lithium battery.
