Greetings,

I am having some trouble finding out how to implement a negative DC shift with an opamp. I am trying to read a sensor that outputs a voltage that ranges from 325 mV to 265 mV. I would like to shift this signal by approximately -265 mV, meaning that I would get a final waveform that ranges from 0 - 60 mV. From there, I can then amplify the signal. Furthermore, I am trying to accomplish this with a single-supply opamp. Any help would be appreciated.

Regards,
Willis
