ROHM Semiconductor BA7655A
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.| Part No. | BA7655A |
