ft2920 Description
The ft2920 is a highly efficient 8W boosted Class-G audio power amplifier with automatic level control (ALC) and battery tracking AGC. It integrates a filterless Class-D audio amplifier with an adaptive multi-level Class-G boost regulator and operates with a range of supply voltages from 3V to 5.5V. When a supply voltage at 3.6V, the ft2920 can deliver an output power of 8W with 10% THD+N, or an ALC output power of...
