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
