ADA4620-2ARZ

ADA4620-2ARZ is a 36V, precision, low noise, low offset drift, dual channel, 16.5MHz JFET op amp with rail-to-rail output. It offers the combination of top precision parameters at speed, and at extended operating range and temperature. The ADA4620 is ideal for high DC precision and AC performance. The specifications make the ADA4620 optimal as a front-end amplifier in a data-acquisition (DAQ) system, or for a TIA circuit with high input impedance. Applications include transimpedance amplifiers, electronic test and measurement, scientific and field instruments, semiconductor test, data acquisition systems, and high impedance sensors.
