9 Detailed Description

9.1 Overview

The LM2904-Q1, LM2904B-Q1, and LM2904BA-Q1 devices consist of two independent, high-gain frequency-

compensated operational amplifiers designed to operate from a single supply over a wide range of voltages.

Operation from split supplies also is possible if the difference between the two supplies is within the supply

voltage. The low supply-current drain is independent of the magnitude of the supply voltage.

Applications include transducer amplifiers, DC amplification blocks, and all the conventional operational amplifier

circuits that now can be implemented more easily in single-supply-voltage systems. For example, these devices

can be operated directly from the standard 5-V supply used in digital systems and easily can provide the

required interface electronics without additional ±5-V supplies.
