Texas Instruments OPAx192/OPAx192-Q1 Rail-to-Rail Precision Op-Amps

Texas Instruments OPAx192/OPAx192-Q1 Rail-to-Rail Precision Operational Amplifiers are the new generation of 36V, e-trim operational amplifiers. These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset (±5μV, typical), low offset drift (±0.2μV/°C, typical), and 10MHz bandwidth. Unique features such as differential input-voltage range to the supply rail, high output current, and high capacitive load drive of up to 1nF, and high slew rate make the OPAx192 a robust, high-performance operational amplifier for high-voltage industrial applications. The OPAx192-Q1 devices are AEC-Q100 qualified for automotive applications.
