Description CXA1202Q-Z/CXA1202R are bipolar ICs developed as REC/PB amplifiers for VCRs. Features • Built-in head amplifier feedback dumping contributes to the reduction of external components and simplification of the print circuit board design. • Built-in BPF for PB signals medium range frequency compensation totally eliminates external resonance circuits (L. C. R.) • Low range recording signal variable-level mix amplifier allows for both metal powder and metal evaporated tapes application. • Consumption saving through power save function of the REC AMP. • 4-head system switch incorporated. Functions • Recording: 2-channel REC AMP, 5-input (Y, Chroma, AFM, ATF, PCM) Mix AMP. • Playback: 2-channel low-noise head amplifier, medium range frequency compensation circuit, RF AGC, dropout detecting circuit. Applications • 8-mm system VCR • β-system VCR • VHS-system VCR
