... A second OPA1013 (A3, A4), connected as a two op amp instrumentation amplifier, amplifies the differential voltage output from the bridge. Gain is easily adjusted with RT. If 1% resistors are used for R4-R7, common-mode rejection will be better than 80dB for gains greater than 200V/V. A CMR of 80dB ...

Preliminary Work
... Important note: Every time you use an op amp chip it must have the power supply pins bypassed with a capacitor to ground. This is standard practice in industry and an op amp should never be used without bypassing. Put capacitors located as close as possible to the IC from the positive supply pin to ...
