STRAIN_GAUGE_INSTRUMENTATION_AMPLIFIER

This circuit has an overall gain of 320. More gain can easily be obtained by lowering the value of R2. UntrimmedVOS is 10 μN, andVOS tempco is less than 0.1 μV/℃. In many circuits, the OP07 can be omit-ted, with the two MAX421 differential outputs connected directly to the differential inputs of an integrating a/d.
