Multimedia ICs 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. •Block diagram VCC 8 IN2 7 CTL2 6 OUT2 5 VCA2 VCA1 1 IN1 2 CTL1 3 OUT1 4 GND 1 Multimedia ICs BA7655A / BA7655AF •Pin descriptions Pin No. 1 2 3 4 5 6 7 8 Pin name IN1 CTL1 OUT [ ... ]
