8 Detailed Description

8.1 Overview

The NE5532, NE5532A, SA5532, and SA5532A devices are high-performance operational amplifiers combining

excellent dc and ac characteristics. They feature very low noise, high output-drive capability, high unity-gain and

maximum-output-swing bandwidths, low distortion, high slew rate, input-protection diodes, and output short-

circuit protection. These operational amplifiers are compensated internally for unity-gain operation. These

devices have specified maximum limits for equivalent input noise voltage.

8.3 Feature Description

8.3.1 Unity-Gain Bandwidth

The unity-gain bandwidth is the frequency up to which an amplifier with a unity gain may be operated without

greatly distorting the signal. The NE5532, NE5532A, SA5532, and SA5532A devices have a 10-MHz unity-gain

bandwidth.

8.3.2 Common-Mode Rejection Ratio

The common-mode rejection ratio (CMRR) of an amplifier is a measure of how well the device rejects unwanted

input signals common to both input leads. It is found by taking the ratio of the change in input offset voltage to

the change in the input voltage and converting to decibels. Ideally the CMRR would be infinite, but in practice,

amplifiers are designed to have it as high as possible. The CMRR of the NE5532, NE5532A, SA5532, and

SA5532A devices is 100 dB.

8.3.3 Slew Rate

The slew rate is the rate at which an operational amplifier can change its output when there is a change on the

input. The NE5532, NE5532A, SA5532, and SA5532A devices have a 9-V/ms slew rate.

8.4 Device Functional Modes

The NE5532, NE5532A, SA5532, and SA5532A devices are powered on when the supply is connected. Each of

these devices can be operated as a single supply operational amplifier or dual supply amplifier depending on the

application.
