OPAx191 36V E-trim Operational Amplifiers

Texas Instruments OPAx191 36V E-trim Operational Amplifiers offer outstanding dc precision and ac performance. This includes rail-to-rail input/output, low offset (±5µV, typ.), low offset drift (±0.2µV/°C, typ.), and 2MHz bandwidth. These amplifiers have unique features such as differential input voltage range to the supply rail and high output current (±65mA). They also include high capacitive load drive of up to 1nF and high slew rate (5V/µs). This makes the OPAx191 a robust, high-performance operational amplifier that is ideal for high-voltage industrial applications. These devices are available in single (OPA191), dual (OPA2191) and quad (OPA4191) packages.
