AD8620ARZ-REEL7

Overview

The AD8620ARZ-REEL7 is a dual-channel precision JFET operational amplifier manufactured by Analog Devices Inc. It features a maximum input offset voltage of 100 μV, a typical gain bandwidth product of 25 MHz, and a slew rate up to 60 V/μs. The device operates on dual supplies ranging from ±5 V to ±13 V with a supply current of approximately 3.5 mA per amplifier. It provides low noise performance with a voltage noise density of 6 nV/√Hz at 1 kHz and maintains stability with capacitive loads exceeding 1000 pF.

Feature Summary

• JFET input architecture providing ultralow bias current and high input impedance
• High-speed dynamic performance with fast settling time and wide bandwidth
• Capable of driving large capacitive loads without external compensation
• Unconditional unity-gain stability with no phase reversal upon overvoltage

Applications

• Photodiode amplifiers
• Automated test equipment (ATE) signal conditioning
• Medical instrumentation including CAT/MRI systems
• Fast precision integrators and filters
• High-performance audio circuits

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to tape and reel packaging as indicated for MSOP devices in official documentation. Confirm that the ARZ suffix denotes the narrow SOIC package variant. Ensure the component matches the Rev F datasheet specifications for extended industrial temperature ranges and electrical characteristics before integration into production designs.

Selection Notes

Select this component when designing circuits requiring high precision combined with wide bandwidth and low noise. It is suitable for applications demanding high output drive capability and stability under heavy capacitive loading conditions. Consider its dual-channel configuration for space-constrained designs where channel separation and matching are critical requirements.

Part Context

This part belongs to the AD8610/AD8620 family of very low noise, low input bias current, wide bandwidth JFET operational amplifiers. The AD8620 variant specifically provides two independent amplifier channels within a single package, sharing the same core XFCB process technology and electrical performance characteristics as the single-channel AD8610.

Replacement Considerations

Officially documented substitutes include the AD8610 for single-channel applications.
