Hi Jac,

AD8638 is the Op amp we recommend using. The resistor values have been updated please see attached document for the latest circuit.

Hi Jim,

Would like to check by implementing this circuitry, the temperature compensation is auto. The amplifier gain will be auto tuned to match the temperature?
