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

• 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 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
