The OPAx197-Q1 family (OPA197-Q1 and OPA2197-Q1) is part of a new generation of 36-V,
e-trim operational amplifiers. The OPAx197-Q1 family of operational amplifiers uses e-trim, a
method of package-level trim for offset and offset temperature drift implemented during the final
steps of manufacturing after the plastic molding process. This method minimizes the influence of
inherent input transistor mismatch, as well as errors induced during package molding.
These devices offer outstanding dc precision and ac performance, including rail-to-rail
input/output, low offset (±5 µV, typical), low offset drift (±0.2 µV/°C, typical), and 10-MHz
Unique features such as differential input-voltage range to the supply rail, high output
current (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (20 V/µs) make the
OPAx197-Q1 a robust, high-performance operational amplifier for high-voltage industrial
The OPAx197-Q1 family of op amps is available in standard packages and is specified from
–40°C to +125°C.
