CXA2002R
2-channel Recording/Playback Amplifier
Description
The CXA2002R is a bipolar IC developed as
recording/playback amplifiers for Hi8 VCRs.
48 pin LQFP (Plastic)
Features
Recording/playback system
Wideband recording/playback amplifier for Hi8
VCR
Supports electronic volume (EVR) control (3V)
Recording system

amplifier and EVR control function of Y and low-
band 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
