The OPAx197 family (OPA197, OPA2197, and OPA4197) is a new generation of 36-V operational amplifiers. These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset (±25 µV, typical), low offset drift (±0.25 µV/°C,
typ), and 10-MHz bandwidth. 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 OPA197 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.
