ADA4622-2ACPZ-R7

ADA4622-2 is a single-supply, rail-to-rail output (RRO), precision junction field effect transistors (JFET) input op-amp. It includes many improvements that make the desirable as upgrades without compromising the flexibility and ease of use that makes the device 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) analogue-to-digital converters (ADCs). It is used in applications such as high output impedance sensor interfaces, photodiode sensor interfaces, transimpedance amplifiers, ADC drivers, precision filters and signal conditioning.
