GENERAL DESCRIPTION

The ADA4622-1/ADA4622-2 are the next generation of the

AD820 and the AD822 single-supply, rail-to-rail output (RRO),

precision junction field effect transistors (JFET) input op amps.

The ADA4622-1/ADA4622-2 include many improvements

that make them desirable as an upgrade without compromising

the flexibility and ease of use that makes the AD820 and the

AD822 useful for a wide variety of applications.

Voltage noise is reduced; while keeping the supply current the

same as the AD820 and the AD822, broadband noise is reduced by

25%, and 1/f is reduced by half. DC precision in the ADA4622-1/

ADA4622-2 improved from the AD820 and the AD822 with

half the offset and a maximum thermal drift specification added

to the ADA4622-1/ADA4622-2. The common-mode rejection

ratio (CMRR) is improved from the AD820 and the AD822 to

make the ADA4622-1/ADA4622-2 more suitable when used in

noninverting gain and difference amplifier configurations.

The input voltage range includes the negative supply and the

output swings rail-to-rail. Input EMI filters increase the signal

robustness in the face of closely located switching noise sources.

The ADA4622-1/ADA4622-2 are specified for operation over the

extended industrial temperature range of −40°C to +125°C and

operates from 5 V to 30 V with specifications at +5 V, 5 V, and

15 V. The ADA4622-1 is available in a 5-lead SOT-23 package

and an 8-lead LFCSP package, and the ADA4622-2 is available in

an 8-lead SOIC package, an 8-lead MSOP package, and an 8-lead

LFCSP package.

The speed, in terms of bandwidth and slew rate, increases along

with a strong output drive to improve settling time performance

and enable the devices to drive the inputs of modern single-ended,

successive approximation register (SAR) analog-to-digital

converters (ADCs).
