BH3854AS /SDIP-32

Процесор сигналів

The BH3854AS and BH3854AFS are signal processing ICs designed for volume and tone control in CD radio cassettesand other audio products. Their three-line serial control enables them to control volume and tone on the basis of signalsfrom a microcomputer, etc.

Applications:

CD radio cassettes, mini component stereo systems, carstereos

Features:

1)   They facilitate direct serial control from a microcom-puter  of  volume  (main  volume)  and  tone  (bass,treble). DC control is also possible.2)   Volume  is  produced  by  a  low-distortion,  low-noiseVCA. Designed to minimize step noise.3)   Input amp can be used for gain adjustment, and ma-trix surround yields powerful sound.4)   Stable standard voltage supply and built-in I / O buff-er mean that few attachments are needed. SSOP32package designed to save space.5)   Open collector has four outputs, which makes logiccontrol possible.6)   Excellent for volume and tone control devices in CDradio  cassettes,  micro  components,  car  stereos,televisions, etc.7)   Digital GND pin and analog GND pin are separatedwith an impedence of more than 1MΩ.
