ft2820, 4W Dual-Pump Class-G Audio Power Amplifier

ft2820 4W Dual-PumpTM Class-G Audio Power Amplifier GENERAL .
The ft2820 is a 4W boosted Class-G audio power amplifier based upon a proprietary Dual-PumpTM topology with automatic level control (ALC).

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 th

Applications

* In ft2820, the power supply rail for the amplifier’s output stage is internally boosted and regulated at 6V by an adaptive charge pump based upon the Dual-PumpTM topology, thus allowing for a much louder audio output than a stand-alone one directly connected to the battery. It makes ft2820 an ideal
