3 Description
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, typ), 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.
