Build
Difference amps instrumentation amps require precision resistors perform their intended function. unity-gain difference amplifier constructed with precision film resistors yields scant 46dB common-mode rejection.hardly precise! Even 0.1% resistors cannot achieve performance quality integrated difference because individual resistors drift same over temperature. on-chip laser-trimmed film resistors these modern difference instrumentation amps track precisely over temperature, maintaining accurate gain characteristics.
