ROHM Semiconductor BA7796FS
The BA7796FS is a 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, an EQ switch, and high-voltage head switch. The IC has three input switching systems, and a built-in coil equivalent circuit for recording equalization, which eliminates the need for an external component.| Part No. | BA7796FS |
