OPA191 Low-Power, Precision, e-trim CMOS Amplifier

OPA191 Low-Power, Precision, e-trim CMOS Amplifier

Texas Instruments' OPA191 is a 36 V, e-trim operational amplifier. This device offers outstanding DC precision and AC performance, including rail-to-rail input/output, low offset (±5 µV, typ), low offset drift (±0.2 µV/°C, typ), and 2 MHz bandwidth.

Unique features such as differential input-voltage range to the supply rail, high output current (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (5 V/µs) make the OPA191 a robust, high-performance operational amplifier for high-voltage industrial applications.

The OPA191 op amp is available in standard packaging and is specified from -40°C to 125°C.
