AD822 Overview

The AD822 is a dual precision, low power FET input op amp that can operate from a single supply of 5 V to 30 V or from dual supplies of ±2.5 V to ±15 V. It has true single-supply capability with an input voltage range extending below the negative rail, allowing the AD822 to accommodate input signals below ground while in the single-supply mode. Output voltage swing extends to within 10 mV of each rail, providing the maximum output dynamic range.

The AD822 drives up to 350 pF of direct capacitive load as a follower and provides a minimum output current of 15 mA. This allows the amplifier to handle a wide range of load conditions. Its combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for the single-supply user. The AD822 is available in two performance grades. The A grade and B grade are rated over the industrial temperature range of −40°C to +85°C. The AD822 is offered in three varieties of 8-lead packages: PDIP, MSOP, and SOIC_N.

This article provides you with a basic overview of the AD822 FET-Input Op-Amp, including its pin descriptions, features and specifications, etc., to help you quickly understand what AD822 is.

Frequently Asked Questions

Is the op amp AD822 the AD8221? What is the difference between these two?
AD822 and AD8221 are not the same, AD822 is an operational amplifier, and AD8221 is an instrumentation amplifier. Among them AD822 is suitable for low power consumption occasions, because its craft is FET craft. The AD8221 is suitable for high-precision amplification, industrial field amplification interfaces and other occasions, because it has excellent common-mode rejection capabilities.
Which of the op amp AD822 or AD823 has good sound quality, and what kind of capacitor does "NP" refer to?
The index of 823 is better than that of 822, but for audio signals, both are sufficient, so you don't need to consider this issue. The capacitor marked NP means that this capacitor is a non-polar capacitor, and the polarity does not need to be considered during installation. It is generally used as a coupling capacitor in the audio signal channel.
