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.

•Applications

Video cassette recorders and tape decks

•Features

1) Three input switching systems built-in (LINE1,

LINE2, and TUNER).

2) Built-in coil equivalent circuit for recording equaliza-

tion.

3) Two-mode EQ switch.

4) High-performance low-noise playback amplifier.

5) Fixed ALC level ( – 7.2dB when VCC = 12V).

6) Phase-inverting recording amplifier.

•Absolute maximum ratings (Ta = 25°C)
