Dual Voltage-controlled Amplifier

BA7655A / BA7655AF

The BA7655A and BA7655AF are dual voltage-controlled amplifier ICs designed for use in camcorders and VCRs.

By varying the control voltage the amplifier gain can varied from -6dB to +6dB. When the control pin voltage drops

below 1V the amplifier enters Power Save Mode which mutes the output and reduces the current drawn by the IC.

•Applications

Video cassette recorders and camcorders

•Features

1) Wide bandwidth.

2) Wide dynamic range.

3) Low power cousumption.

4) Output muting possible.

5) Low voltage gain temperature drift.
