AD8620ARZ-REEL

AD8620 is a very high precision JFET input amplifier featuring ultralow offset voltage and drift, very low input voltage and current noise, very low input bias current, and wide bandwidth. Unlike many JFET amplifiers, this device input bias current is low over the entire operating temperature range. This device is stable with capacitive loads of over 1000pF in non-inverting unity gain; much larger capacitive loads can be driven easily at higher noise gains. It swings to within 1.2V of the supplies even with a 1Kohm load, maximizing dynamic range even with limited supply voltages. Outputs slew at 50V/μs in either inverting or non-inverting gain configurations, and settle to 0.01% accuracy in less than 600ns. It is used in applications such as photodiode amplifiers, ATE, instrumentation, sensors and controls, high performance filters, fast precision integrators, high performance audio.
