BA7655AF
BA7655AF is manufactured by ROHM.
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.
