General Description

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 with 10% THD+N.

Overview

ft2820 4W Dual-PumpTM Class-G Audio Power Amplifier GENERAL.

Key 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.
