The OPAx192-Q1 family (OPA192-Q1 and OPA2192-Q1) is a new generation of 36-V, e-trim operational amplifiers. The OPAx192-Q1 family of operational amplifiers use e-trim, a method of package-level trim for offset and offset temperature drift implemented during the final steps of manufacturing after the plastic molding process. This method minimizes the influence of inherent input transistor mismatch, as well as errors induced during package molding.

These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset (±5 µV, typical), low offset drift (±0.2 µV/°C, typical), 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 OPAx192-Q1 a robust, high-performance operational amplifier for high-voltage industrial applications.

The OPAx192-Q1 family of op amps is available in an 8-pin VSSOP package and is specified from –40°C to +125°C.
