ADA4620-1ARZ-R7

Overview

The ADA4620-1ARZ-R7 is a single-channel precision JFET operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 16 MHz and a slew rate of 34 V/µs, supporting a supply voltage range from 4.5 V to 36 V. The device offers low input bias current of 0.8 pA and input offset voltage of 30 µV. It is housed in an 8-SOIC surface-mount package with an operating temperature range of -40°C to +125°C.

Feature Summary

• Precision JFET input stage for high DC accuracy
• Rail-to-rail output capability
• Low input bias current and offset voltage

Applications

• High precision signal conditioning
• Sensor interface circuits
• Data acquisition systems

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the component matches the single-channel variant within the ADA4620 family. Ensure the manufacturer is Analog Devices Inc. Check RoHS compliance status through official documentation before integration.

Selection Notes

Select this part for applications requiring high DC precision combined with moderate AC performance. The rail-to-rail output allows for maximum dynamic range in single-supply systems. Consider the 8-SOIC package constraints for PCB layout. Compare against dual-channel variants if multiple amplifiers are needed.

Part Context

This component belongs to the ADA4620 series of precision JFET operational amplifiers. The series is designed for applications demanding high DC accuracy and good AC performance. The single-channel configuration distinguishes it from dual-channel counterparts like the ADA4620-2.

Replacement Considerations

ADA4620-1ARZ is the tube-packaged equivalent. ADA4620-1ARZ-RL is another reel variant. Verify pinout and electrical specifications match exactly before substitution.
