GENERAL DESCRIPTION

The ADA4622-1/ADA4622-2/ADA4622-4 are the next generation

of the AD820/AD822/AD824 single-supply, rail-to-rail output

(RRO), precision junction field effect transistors (JFET) input

op amps. The ADA4622-1/ADA4622-2/ADA4622-4 include

many improvements that make them desirable as upgrades

without compromising the flexibility and ease of use that makes

the AD820/AD822/AD824 useful for a wide variety of applications.

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

with a strong output drive to improve settling time performance

and enables the devices to drive the inputs of modern single-

ended, successive approximation register (SAR) analog-to-

digital converters (ADCs).

Voltage noise is reduced; although the supply current remains

the same as the AD820/AD822/AD824, broadband noise is

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

ADA4622-1/ADA4622-2/ADA4622-4 improved from the

AD820/AD822/AD824 with half the offset and a maximum

thermal drift specification added to the ADA4622-1/ADA4622-2/

ADA4622-4. The common-mode rejection ratio (CMRR) is

improved from the AD820/AD822/AD824 to make the

ADA4622-1/ADA4622-2/ADA4622-4 more suitable when used in

noninverting gain and difference amplifier configurations.

The ADA4622-1/ADA4622-2/ADA4622-4 are specified for

operation over the extended industrial temperature range of −40°C

to +125°C, and operate 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. The ADA4622-2

is available in an 8-lead SOIC_N package, an 8-lead MSOP

package, and an 8-lead LFCSP package. The ADA4622-4 is

available in a 14-lead SOIC_N and a 16-lead, 4 × 4 mm LFCSP.
