OPA197-Q1 - 36-V, Precision, Rail-to-Rail Input Output, Low Offset Voltage Op Amp

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, amethod of package-level trim for offset and offset temperature drift implemented during the finalsteps of manufacturing after the plastic molding process. This method minimizes the influence ofinherent input transistor mismatch, as well as errors induced during package molding.

These devices offer outstanding dc precision and ac performance, including rail-to-railinput/output, low offset (±5 µV, typical), low offset drift (±0.2 µV/°C, typical), and 10-MHzbandwidth.

Unique features such as differential input-voltage range to the supply rail, high outputcurrent (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (20 V/µs) make theOPAx197-Q1 a robust, high-performance operational amplifier for high-voltage industrialapplications.

The OPAx197-Q1 family of op amps is available in standard packages and is specified from–40°C to +125°C.
