Description
The FAB2210 combines a Class-G stereo capacitor-
free headphone amplifier with a mono Class-D
speaker amplifier into one IC package.
The headphone and speaker amplifiers incorporate
Class-G and Class-D topologies, respectively, for low
power dissipation, which extends battery runtime.
The Class-G headphone amplifier incorporates an
integrated charge pump that generates a negative
supply rail for ground-centered headphone outputs.
The
Class-D
amplifier
includes
programmable
Dynamic Range Compression (DRC) that maximizes
Sound Pressure Level (SPL) for maximum loudness,
while protecting the speaker from damage.
The noise gate can automatically mute the speaker or
headphone amplifiers to reduce noise when input
signals are LOW.
