VCR standard audio signal processor

BA7796FS

The BA7796FS is a standard audio signal processor designed for use in VCRs and tape decks. The circuit is com-

prised of a playback preamplifier, a line amplifier, a recording amplifier, an ALC circuit, an EQ switch, and high-volt-

age head switch.

The IC has three input switching systems, and a built-in coil equivalent circuit for recording equalization, which elimi-

nates the need for an external component.
