The ADA4620-1 and ADA4620-2 are a series of 36 V, precision, low noise, low offset drift, JFET Op Amps. The parts offer the combination of top precision parameters at speed, and at extended operating range and temperature. The ADA4620 is ideal for customers who need to design systems to meet 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.

For only 1.3 mA of supply current per amplifier, the ADA4620 has a gain-bandwidth product of 16 MHz, a 30 V/μs slew rate, 5 nV/√Hz of broadband noise, and 200 nV p-p of 1/f noise. The input voltage range includes the negative supply, and the output swings rail-to-rail.

The ADA4620 is specified for operating over the temperature range of −40°C to +125°C, and dual supplies ranging from ±2.25 V to ±18 V, or on a single supply ranging from +4.5 V to +36 V. The ADA4620- 1 and ADA4620-2 are available in an 8-lead SOIC_N package.
