CXA1702AR

CXA1702AR 4-channel REC/PB Amplifier for 8 mm VCR Description The CXA1702AR is a bipolar IC designed as recording/playback amplifiers for Hi8-compatible VCRs. Features Recording/playback system Hi8-compatible wideband recording/playback amplifier. Enables electric variable resistor (EVR) control. 64 pin LQFP (Plastic) Recording system Feedback damping provided in the recording amplifier and its EVR control function facilitate printed circuit board design. Five-input (Y, chroma, AFM, ATF, PCM) mix amplifier and EVR control function for Y/low-band recording level. Ramp circuit for the recording amplifier output bias current. Application 8 mm VCR Structure Bipolar silicon monolithic IC Absolute Maximum Ratings (Ta = 25°C) Supply voltage VCC 7 Playback system Feedback dumping provided in the playback amplifier facilitates printed circuit board design. Middle-frequency tuner on chip; EVR permits independent adjustment of its center frequency fo, Q and boost amount by EVR. RF AGC and dropout detection circuit.
