9 Detailed Description

9.1 Overview

The LM2904-Q1 and LM2904B-Q1 consist of two independent, high-gain frequency-compensated operational

amplifiers designed to operate over a wide range of voltages. The LM2904B-Q1 operates from 3 V to 36 V,

whereas the LM2904-Q1 operates from 3 V to 26 V and the V-versions (LM2904V-Q1 and LM2904AV-Q1)

operate from 3 V to 32 V. The input common-mode range is inclusive of the negative supply rail, enabling a

common-mode voltage operation down to ground, if using the device in a single-supply operation.
