s BA3430S / BA3430F / BA3430FS 271 Audio ICs BA3430S / BA3430F / BA3430FS FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 9V, f = 1kHz, Rg = 680Ω, VO = *10dBV) 272 Audio ICs FMeasurement circuit BA3430S / BA3430F / BA3430FS FAudio signal amplification circuit (1) Input switch circuit This circuit switches between head A and head B as needed for the auto reverse function.
A 10kΩ or less resistor must be connected to the input pin to limit the input current.
Equivalent circuit schematic The electrolytic capacitor between the input pin and ground is for preventing switch noise.
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 parallel inputs and outputs, and enables a very compact circuit configuration around the tape head.
