Overview
The OPA2192-Q1 is a high-performance, 36-V, rail-to-rail input/output operational amplifier from Texas Instruments. This device is part of the OPAx192-Q1 family, which includes the OPA192-Q1 and OPA2192-Q1 models. The OPA2192-Q1 is manufactured using TI's e-trim technology, which minimizes input offset voltage and drift by implementing package-level trim during the final steps of manufacturing. This results in outstanding DC precision and AC performance, making it suitable for high-voltage industrial applications.
