Product Introduction
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 singleended, successive approximation register (SAR) analog-todigital 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.
