The ft2830 is a highly efficient 4.5W Class-G audio power amplifier with automatic level control (ALC) for use in battery-powered portable devices.

It integrates a filterless Class-D audio power amplifier with a Class-G charge pump regulator based upon proprietary Dual-PumpTM topology.

It operates from 3.2V to 4.6V supply.

ft2830 4.5W Dual-PumpTM Class-G Audio Power Amplifier GENERAL.

ALC to constantly monitor and safeguard the audio outputs against the boosted supply voltage, preventing output clipping distortion, excessive power dissipation, or hazardous speaker over-load. Once an over-level condition is detected, the ALC lowers the voltage gain of the audio amplifier proportionally to eliminate output clipping distortion while maintaining a maximum dynamic range of the audio outputs allowed by the boosted supply voltage.
