This document describes the features and characteristics of the OPA241 series and OPA251 series single-supply, micropower operational amplifiers from Burr-Brown Corporation. These amplifiers are designed for battery-powered portable applications and feature low power consumption, single-supply operation, rail-to-rail output swing, wide supply range, low offset voltage, high common-mode rejection, and high open-loop gain.
The document describes the OPA241 series (optimized for +5V supply) and the OPA251 series (optimized for ±15V supply). Both series feature MicroPOWER technology with a quiescent current of 25µA, rail-to-rail output swing within 50mV of the rails, and high common-mode rejection. They are designed for battery-operated instruments, portable devices, medical equipment, and test applications.
