7.1 Overview

The OPA4991-EP is a new 40-V general purpose operational amplifier.

This device offers excellent DC precision and AC performance, including rail-to-rail input/output, low offset (±125 µV, typ), low offset drift (±0.3 µV/°C, typ), and 4.5-MHz bandwidth.

Unique features such as differential and common-mode input-voltage range to the supply rail, high output current (±75 mA) and high slew rate (21 V/µs) make the OPA4991-EP a robust, high-performance operational amplifier for high-voltage automotive applications.
