Dear all,
I'm trying to build a strain gauge bridge signal conditioning circuit. I'm interested in measuring microvolt differences in signal. This variation will sit on an offset of up to 20mV. I've so far designed the attached circuit.
I would be very grateful for any advice on the attached circuit and particularly how to add an offset trim to remove the comparatively large offset.
Many thanks for your time.
