ADA4620-1ARZ-RL

Overview

The ADA4620-1ARZ-RL is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It features JFET input technology designed for high DC accuracy and AC performance. The device operates within a supply voltage range of 4.5 V to 36 V and delivers a gain-bandwidth product of 16 MHz with a slew rate of 34 V/µs. Key electrical specifications include an input offset voltage of 30 µV, input bias current of 0.8 pA, and output current capability of 94 mA. It is housed in an 8-SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• JFET input architecture providing low input bias current and high input impedance
• Rail-to-rail output capability for maximum dynamic range utilization
• High DC precision characterized by low input offset voltage and drift
• Single-channel configuration optimized for space-constrained designs

Applications

• Precision signal conditioning circuits requiring high DC accuracy
• Battery-powered instrumentation utilizing low supply currents
• Industrial process control systems demanding stable amplification
• Medical equipment interfaces necessitating low noise performance

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing components. Confirm that the part number corresponds to the single-channel variant rather than the dual-channel ADA4620-2 series. Ensure compatibility with standard 8-SOIC footprints during PCB layout verification. Cross-reference manufacturer documentation for any recent lifecycle status updates or recommended design-in guidelines.

Selection Notes

Select this component when application requirements prioritize low input bias current alongside moderate bandwidth. Compare against rail-to-rail CMOS alternatives if lower quiescent current is critical. Evaluate thermal management needs given the wide operating temperature range. Consider the ADA4620-2 variant if dual-channel functionality is required within the same footprint constraints.

Part Context

This part belongs to the ADA4620 family of precision JFET operational amplifiers from Analog Devices. The family is engineered to bridge the gap between general-purpose amplifiers and high-performance chopper-stabilized devices. The single-channel version offers flexibility in system design while maintaining the core precision characteristics of the series.

Replacement Considerations

ADA4620-1ARZ is the tube-packaged equivalent of this reel-part. ADA4620-1ARZ-R7 is another reel option available from distributors.
