3 wire serial sound control IC
BH3862FS
Description
BH3862FS is a sound control IC that includes
a 4 input selector, volume and a 2 band tone.
REC output terminals are located between the
4 input selector and the volume. Either 0dB or
18dB gain can be chosen. Functions such as
stereo/monaural mode selection and mute are
provided.
Dimension (Units : mm)
99W088A
Features
1) Built-in 4-input selector, mute circuit,
REC gain amplifier, volume, bass and treble.
2) 3-wire serial interface
3) Resistor ladder type volume control that uses a
BiCMOS process for low noise and distortion.
4) SSOP-A24 package
SSOP-A24
Applications
Mini component stereo, Micro component stereo,
Radio cassette recorder
