The ADA4622-1/ADA4622-2/ADA4622-4 are the next generation Voltage noise is reduced; although the supply current remains of the AD820/AD822/AD824 single-supply, rail-to-rail output the same as the AD820/AD822/AD824, broadband noise is (RRO), precision junction field effect transistors (JFET) input reduced by 25%, and 1/f is reduced by half. DC precision in the op amps. The ADA4622-1/ADA4622-2/ADA4622-4 include ADA4622-1/ADA4622-2/ADA4622-4 improved from the many improvements that make them desirable as upgrades AD820/AD822/AD824 with half the offset and a maximum without compromising the flexibility and ease of use that makes thermal drift specification added to the ADA4622-1/ADA4622-2/ the AD820/AD822/AD824 useful for a wide variety of applications. ADA4622-4. The common-mode rejection ratio (CMRR) is The input voltage range includes the negative supply and the improved from the AD820/AD822/AD824 to make the output swings rail-to-rail. Input EMI filters increase the signal ADA4622-1/ADA4622-2/ADA4622-4 more suitable when used in robustness in the face of closely located switching noise sources. noninverting gain and difference amplifier configurations. The speed, in terms of bandwidth and slew rate, increases along The ADA4622-1/ADA4622-2/ADA4622-4 are specified for with a strong output drive to improve settling time performance operation over the extended industrial temperature range of −40°C and enables the devices to drive the inputs of modern single- to +125°C, and operate from 5 V to 30 V, with specifications at ended, successive approximation register (SAR) analog-to- +5 V, ±5 V, and ±15 V. The ADA4622-1 is available in a 5-lead digital converters (ADCs). 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.
