ZHCSEI8C January 2016 – March 2018 OPA197 , OPA2197 , OPA4197
PRODUCTION DATA.
The OPAx197 uses a patented two-temperature trim architecture to achieve a very low offset voltage of 250 µV (max) and low voltage offset drift of 0.75 µV/°C (maximum) over the full specified temperature range. This level of precision performance at wide supply voltages makes these amplifiers useful for high-impedance industrial sensors, filters, and high-voltage data acquisition.
