Video ICs 2-channel PRE / REC amplifier with auto-tracking interface BA7180AS / BA7180AFS The BA7180AS and BA7180AFS are PRE / REC amplifiers developed for use in video cassette recorders. They have been designed for use in two-head decks and feature 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 VHSband operation with low external parts count.The ICs have 2 circuits for 2-head VCR applications.
