Analog Switch ADG5434

Hello,

I am using ADG5434 in closed loop feedback applications but my switch is working as desired. Please refer the below circuit which depict how i have use the switch.

  • Actually we are using a negative feedback amplifier. In the feedback loop we have use the analog switch in parallel with a higher value resistance. When we are feeding the input the amplifier then gain is not achieved as desired and we think that the switch is not working as it should. We have used the switch in normally connected condition and when the input is fed to the amplifier the the switch goes to NO condition such that the gain of the amplifier becomes high.

    Please let me know if you still have any doubt regarding the schematic.
