The ft2850 is a 5W Dual-PumpTM Class-AB/D/G audio power amplifier with automatic level control (ALC) for portable audio applications.

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

It operates from 3.2V to 4.6V supply.

ft2850 5W Dual-PumpTM Class-AB/D/G Audio Power Amplifier GENERAL.

ALC that constantly monitors and safeguards the audio output against the boosted supply voltage, preventing output clipping distortion, excessive power dissipation, or speaker over-load. Once an over-level condition is detected, the ALC lowers the voltage gain of the audio amplifier proportionally to limit the peak audio output voltage.
