8 Detailed Description

8.1 Overview

The NE5534, NE5534A, SA5534, and SA5534A devices are high-performance operational amplifiers combining

excellent dc and ac characteristics. Some of the features include very low noise, high output-drive capability, high

unity-gain and maximum-output-swing bandwidths, low distortion, and high slew rate.

These operational amplifiers are compensated internally for a gain equal to or greater than three. Optimization of

the frequency response for various applications can be obtained by use of an external compensation capacitor

between COMP and COMP/BAL. The devices feature input-protection diodes, output short-circuit protection, and

offset-voltage nulling capability with use of the BALANCE and COMP/BAL pins (see the Application Circuit

Diagram).

For the NE5534A and SA5534A devices, a maximum limit is specified for the equivalent input noise voltage.
