描述 Description

Serial sound control ICThe BH3854AS and BH3854AFS are signal processing ICs designed for volume and tone control in CD radio cassettes and other audio products. Their three-line serial control enables them to control volume and tone on the basis of signals from a microcomputer, etc.\u0001

特性 Features

1) They facilitate direct serial control from a microcomputer of volume (main volume) and tone (bass, treble). DC control is also possible.
2) Volume is produced by a low-distortion, low-noise VCA. Designed to minimize step noise.
3) Input amp can be used for gain adjustment, and matrix surround yields powerful sound.
4) Stable standard voltage supply and built-in I / O buffer mean that few attachments are needed. SSOP32 package designed to save space.
5) Open collector has four outputs, which makes logic control possible.
6) Excellent for volume and tone control devices in CD radio cassettes, micro components, car stereos, televisions, etc.
7) Digital GND pin and analog GND pin are separated with an impedence of more than 1MΩ.\u0001Applications
CD radio cassettes, mini component stereo systems, car stereos
