Stereo sound controller IC

BA3853BFS

The BA3853BFS is a dual-channel electronic volume controller built around a low-noise, low-distortion VCA. It is suited
for car-audio applications, and has performance that rivals mechanical-type volume controllers.
In addition to volume control, the IC includes all functions required for controlling sound quality, to allow more compact
designs with far fewer components.

Applications
Car audio systems

Features

1) Provides electronic control for volume, balance, fad­er, tone (bass and treble), and loudness.

2) The volume control circuit is a low-distortion, low­noise VCA circuit that uses DC voltage for control.
The IC uses an internally-generated, temperature­compensated reference voltage and is capable of
dual-channel control with the addition of a single po­tentiometer.

3) Available in an SSOP-24 package that is ideal for
compact designs.
