The extremely low offset (150µV max) and drift (1.5µV/°C) are achieved by trimming the IC digitally after packaging to avoid the shift in parameters as a result of stresses during package assembly. To correct for offset drift, the OPA727 and OPA728 family is trimmed over temperature. The devices feature very high CMRR and open-loop gain to minimize errors. Excellent ac ch...
