8 Detailed Description

8.1 Overview

The TL08xx JFET-input operational amplifier family is designed to offer a wider selection than any previously

developed operational amplifier family. Each of these JFET-input operational amplifiers incorporates well-

matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high

slew rates, low input bias and offset currents, and low offset-voltage temperature coefficient. Offset adjustment

and external compensation options are available within the TL08xx family.

The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for

operation from

−40°C to 85°C. The Q-suffix devices are characterized for operation from –40°C to +125°C. The

M-suffix devices are characterized for operation over the full military temperature range of

−55°C to +125°C.

8.3 Feature Description

8.3.1 Total Harmonic Distortion

Harmonic distortions to an audio signal are created by electronic components in a circuit. Total harmonic

distortion (THD) is a measure of harmonic distortions accumulated by a signal in an audio system. These devices

have a very low THD of 0.003% meaning that the TL08x devices will add little harmonic distortion when used in

audio signal applications.

8.3.2 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. These devices have a 13-V/

μs slew rate.

8.4 Device Functional Modes

These devices are powered on when the supply is connected. This device can be operated as a single-supply

operational amplifier or dual-supply amplifier depending on the application.
