BH3810FS

The BH3810FS is a vocal fader IC that is serial control compatible. It has mode switching that also includes a voice

multiplexing mode, a five-input selector, a gain selector and other such features, which can all be controlled serially.

Eight open-collector terminals and two tri-state terminals are provided on the chip to facilitate control by other ICs.

Applications

•

Component stereo systems, CD radio cassette players, TVs and car stereos.

Features

•

1) Built-in low-pass filter can perform vocal fader func-

tion (erasing of vocals from commercially available

music software) using just one chip.

4) Five-channel input selector.

5) Mic. mixing amplifier with mute function. Key con-

troller input also provided.

2) Serial control can be used to switch between vocal

fader, through, multiplex, and mute modes.

3) Built-in gain selector allows selection of gain from

6dB to 20dB in 2dB steps.

6) SSOP-A32 pin package.
