Dual-channel electronic volume controller

Leave a Comment
General Description:
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.
