The OPAx191 family (OPA191, OPA2191, OPA4191) is a new generation of 36-V, e-trim operational amplifiers.
These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset voltage (±5 µV, typ), low offset drift (±0.2 µV/°C, typ), and 2-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 (5 V/µs) make the OPAx191 a robust, high-performance operational amplifier for high-voltage industrial applications.
The opax191 family of op amps is available in standard packages and is specified from –40°C to +125°C.
