VCR standard audio signal processor
The BA7797F is standard audio signal processor designed for use in VCRs and tape decks. The circuit is comprised of a playback preamplifier, a line amplifier, a recording amplifier, an ALC circuit and high-voltage head switch. The IC has a built-in coil equivalent circuit for recording equalization, which eliminates the need for an external component.
FEATUREs
1) Two input switching systems built-in (LINE and TUNER).
2) Built-in coil equivalent circuit for recording equalization.
3) High-performance low-noise playback amplifier.
4) ALC level can be adjusted by connection of an external resistor.
5) Compatible with single-mode EQ making it ideally suited to widely-used decks.
Applications
Video cassette recorders and tape decks
