Analog Devices Inc. ADA4620-1/-2 Precision JFET Op Amps
Analog Devices Inc. ADA4620-1 and ADA4620-2 Precision JFET Op Amps are 36V, low noise, and low offset drift op amps available in 8-lead SOIC_N packages. These devices offer the combination of top precision parameters at speed and extended operating range and temperature. The specifications make the ADA4620 devices optimal as a front-end amplifier in a Data Acquisition (DAQ) system or a Trans-impedance Amplifier (TIA) circuit with high-input impedance. The ADA4620 op amps consume just 1.3mA per amplifier, delivering a 16.5MHz gain-bandwidth product, 32V/μs slew rate, and 5.1nV/√Hz broadband noise. These op amps offer 225nVp-p noise from 0.1Hz to 10Hz, with a negative supply input voltage range and rail-to-rail output swings.
The ADA4620-1/-2 JFET op amps are ideal for high DC precision and AC performance. These JFET op amps operate across a -40°C to 125°C temperature range, with dual supplies of ±2.25V to ±18V or a single supply range of 4.5V to 36V. Typical applications include trans-impedance amplifiers, electronic test and measurements, scientific and field instruments, semiconductor tests, data acquisition systems, and high-impedance sensors.
