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, fad-
er, tone (bass and treble), and loudness.
2) The volume control circuit is a low-distortion, low-
noise VCA circuit that uses DC voltage for control.
The IC uses an internally-generated, temperature-
compensated reference voltage and is capable of
dual-channel control with the addition of a single po-
tentiometer.
3) Available in an SSOP-24 package that is ideal for
compact designs.
