8 Detailed Description

8.1 Overview

These 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

more positive than the input common-mode 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.
