Product Details

The ADA4622-2 is the next generation of the AD822 single-supply, rail-to-rail output (RRO), precision junction field effect transistors (JFET) input op amp. The ADA4622-2 includes many improvements that make it desirable as an upgrade without compromising the flexibility and ease of use that makes the AD822 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 are added to increase the signal robustness in the face of closely located switching noise sources.

The speed in terms of bandwidth and slew rate is increased along with a strong output drive to improve settling time performance and enable the device to drive the inputs of modern single-ended, successive approximation register (SAR) analog-to-digital converters (ADCs).

Voltage noise is reduced; broadband noise is reduced by 25% and 1/f is reduced by half while keeping the supply current the same as the AD822. DC precision in the ADA4622-2 improved from the AD822 with half the offset and a maximum thermal drift specification added to the ADA4622-2. The commonmode rejection ratio (CMRR) is improved from the AD822 to make the ADA4622-2 more suitable when used in noninverting gain and difference amplifier configurations.

The ADA4622-2 is 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 ADA4622-2 is available in 8-lead SOIC, 8-lead MSOP, and 8-lead LFCSP packages.
