Description
The ft2920 is a highly efficient 8W boosted Class-G audio power amplifier with automatic level control (ALC) and battery tracking AGC.
Features
- ALC function to constantly monitor and safeguards the audio output against the boosted supply voltage of the audio amplifier’s output stage, preventing output clipping distortion, excessive power dissipation, and 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. In conjunction with ALC, as the battery supply voltage drops, the battery tracking AGC lowers the voltage gain of the audio.
