CXA1202R Datasheet | Sony Semiconductor Solutions

Description CXA1202Q-Z/CXA1202R are bipolar ICs developed as REC/PB amplifiers for VCR's. Features - Built-in head amplifier feedback dumping contributes to the reduction of external ponents and simplification of the print circuit board design. - Built-in BPF for PB signals medium range frequency pensation 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 pensation circuit, RF AGC, dropout detecting circuit.
