Overview
The OPA192-Q1, produced by Texas Instruments, is a high-voltage rail-to-rail input/output precision operational amplifier. This device is part of the OPAx192-Q1 family, which includes the OPA192-Q1 and OPA2192-Q1. It is designed 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 approach ensures outstanding DC precision and AC performance. The OPA192-Q1 is available in an 8-pin VSSOP package and is specified to operate over a temperature range of –40°C to +125°C, making it suitable for high-voltage industrial and automotive applications.
