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.
