Video ICs 2-channel PRE / REC amplifier with auto-tracking interface BA7181FS The BA7181FS is a PRE / REC amplifier developed for use in video cassette recorders. It has been designed for use in two-head decks and features built-in FB damping, two preamplifiers, a chroma output amplifier, an FM output amplifier (with AGC), an envelope detector, a constant-current BTL-drive REC amplifier (with AGC)and built-in channel and REC / PB switches on a single monolithic IC. Applications • VCRs Features • 1) The playback amplifier has a total gain of 57dB (Typ.), and has a low-noise preamplifier. Designed for VHS-band operation with low external parts count. The IC has two circuits for two-head VCR applications. 2) Two playback output systems (through output and AGC output).
