Hi,

   I am trying to configure Transimpedance  Amplifier using AD8616 for my colorimeter Application.  Please find the attached block. I am getting swings 700uV to 1mV variation (either Increase or Decrease pattern) in the output. Please find attached graph. Why i am getting swings in the output, is there any mistake in my configuration? Please suggest...

 

 

 

Thanks

Vanaja.
