TI OPA2191IDGKT

The OPAx191 series (OPA191, OPA2191, and OPA4191) is a new generation of 36V e-trim™ operational amplifiers. These devices feature excellent DC accuracy and AC performance, including rail-to-rail input/output, low offset voltage (typical: ±5μV), low offset drift (typical: ±0.2μV/°C), and a 2MHz bandwidth. The OPAx191 has unique features such as a differential input voltage range up to the supply rails, high output current (±65mA), high capacitive load drive up to 1nF, and a high slew rate (5V/μs). It is a stable and reliable high-performance operational amplifier suitable for various high-voltage industrial applications. The OPAx191 series operational amplifiers are available in standard packages and operate over a rated temperature range of -40°C to +125°C.
