ft2820 Overview
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.
