Subsystem with Stereo Class-G Headphone Amplifier and Mono Class-D Speaker Amplifier

General Description

The FAB2200 combines a capacitor-free stereo headphone amplifier with a monolithic class-D speaker amplifier.

An integrated charge pump generates multiple supply rails for a ground-centered class-G headphone output. The charge pump is regulated for high Power Supply Rejection Ratio (PSRR).

The filterless class-D amplifier can be connected directly to a speaker without external filters.

The programmable Automatic Gain Control (AGC) limits maximum speaker output levels to protect speakers without introducing distortion. It can also dynamically limit clipping as the battery voltage falls.

The noise gate can automatically mute the speaker or headphone amplifiers to reduce noise when input signals are LOW.
