3 Description
The OPAx192 family (OPA192, OPA2192, and
OPA4192) 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 (±5 µV, typ), low offset drift (±0.2 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 OPA192 a robust, high-
performance operational amplifier for high-voltage
industrial applications.
The OPA192 family of op amps is available in
standard packages and is specified from –40°C to
+125°C.
