Audio ICs 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 designed 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
