BD3871FS
Description
BD3871FS is a sound processor for CD/MD radio
cassette player. This IC provides all functions,
such as input selector (3 input sources), an input
gain amplifier (25dB, 27dB, 29dB),and a surround,
tone (bass, treble). This IC can be controlled
by a 2-wire serial data interface.

Features
1) Can select center frequency and Q value of Bass
characteristics by external components.
2) Mute switch at the input terminal can reduce cross talk.
3) Surround function is composed without external components.
4) Ideal for energy-saving designs with low current consumption
due to the adoption of the BiCMOS process, allowing easy-design
of the regulator blocks in the set.
