Overview
CXA2002R 2-channel Recording/Playback Amplifier Description The CXA2002R is a bipolar IC developed as recording/playback amplifiers for Hi8 VCRs.
Features • Recording/playback system • Wideband recording/playback amplifier for Hi8 VCR • Supports electronic volume (EVR) control (3V) • Recording system • Recording amplifier feedback dumping circuit and its EVR control function facilitates printed circuit board design.
• Five-input (Y, chroma, AFM, ATF and PCM) mix amplifier and EVR control function of Y and lowband recording level • Ramp circuit for the recording amplifier output bias current • Playback system • Playback amplifier feedback dumping circuit facilitates printed circuit board design.
• Middle-band compensation circuit (middle tune) and independent adjustments of the center frequency, Q and boost by EVR • RFAGC and dropout detection circuits Absolute Maximum Ratings • Supply voltage VCC 7 • Operating temperature Topr –10 to +75 • Storage temperature Tstg –65 to +150 • Allowable power dissipation PD 1100 (when mounted on the printed circuit board) Recommended Operating Condition • Supply voltage • Vcc EVR voltage 48 pin LQFP (Plastic) Application 8 mm VCR Structure Bipolar silicon monolithic IC V °C °C mW 4.
