Stereo Pre-amplifiers With Mute Detection Circuits For Car Stereos

The BA3430S, BA3430F and BA3430FS are stereo pre-amplifiers with mute detection circuits which have been de- signed for use in car stereos. The Analog circuitry including the pre-amplifier and mute detection and the digital circuitry such as control Logic circuits have been combined together on a single chip. This has made it possible to reduce the Interface with the Microcontroller to five parallel inputs and outputs, and enables a very compact circuit configuration around the tape head. The BA3430S, BA3430F or BA3430FS makes it possible to easily incorporate an ultra-compact, high-precision pre-am- plifier board into the mechanical components of a car stereo. By ROHM Co. Ltd.
