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

The OPAx197 family (OPA197, OPA2197, and OPA4197) is a new generation of 36-V operationalamplifiers.

These devices offer outstanding dc precision and ac performance, including rail-to-railinput/output, low offset (±25 µV, typical), low offset drift (±0.25 µV/°C, typ), 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 theOPA197 a robust, high-performance operational amplifier for high-voltage, industrial applications.

The OPA197 family of op amps is available in standard packages and is specified from–40°C to +125°C.
