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.
