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 el.

In ft2820, the power supply rail for the amplifier’s output stage is internally boosted and regulated at 6V by an adapt.

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 sp.
