ADA4622-4ARZ

ADA4622-4 is a single-supply, rail-to-rail output (RRO), precision junction field effect transistor (JFET) input opamps. 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 widely used in application such as high output impedance sensor interfaces, photodiode sensor interfaces, transimpedance amplifiers, ADC drivers, precision filters and signal conditioning etc.
