OPA191IDBVR

The OPAx191 family (OPA191, OPA2191, and
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, highperformance 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.
