Stereo pre-amplifiers with mute

detection circuits for car stereos

BA3430S / BA3430F / BA3430FS

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.
