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

The ft2820 is a 4W boosted Class-G audio power amplifier based upon a proprietary Dual-PumpTM topology with automatic level control (ALC). It operates from 3V to 5.5V supply. When operating with a 4.2V supply voltage, it is capable of driving a 4Ω speaker load at a continuous average output of 4W wi.

ft2820 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
