Implement a negative DC shift with an OpAmp

[willis...]

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

A basic differential amplifier can do.


From https://www.analog.com/library/analogDialogue/archives/39-05/op_amp_applications_handbook.html

Producing 0 to 50 mV with a single supply OP will be problematic, because you can't achieve exactly zero output.
