AD8620BRZ

Overview

The AD8620BRZ is a dual-channel, precision JFET input operational amplifier manufactured by Analog Devices. It features a gain bandwidth product of 25 MHz and a slew rate of 60 V/μs at ±13 V supplies. Key electrical specifications include a maximum offset voltage of 100 μV, an input bias current of 10 pA maximum, and a voltage noise density of 6 nV/√Hz. The device operates on dual supplies ranging from ±5 V to ±13 V, consumes approximately 3.5 mA per amplifier, and is housed in an 8-lead SOIC package.

Feature Summary

• Features ultralow input bias current that remains low across the entire operating temperature range.
• Provides high output drive capability with fast settling times for driving capacitive loads.
• Ensures unconditional stability in all gain configurations without phase reversal.

Applications

• Photodiode amplifiers
• High performance filters
• Fast precision integrators
• Electronic instrumentation

Procurement Notes

Verify the specific suffix BRZ against official documentation to confirm the exact temperature grade and packaging configuration. Ensure the procurement channel provides valid traceability for the Analog Devices manufacturer. Confirm that the component matches the required industrial temperature range specifications before integration into the design.

Selection Notes

Select this component when designing circuits requiring very low input bias current combined with wide bandwidth. It is suitable for applications demanding high precision and low noise, such as sensor interfaces or data acquisition systems. Consider its dual-channel architecture for space-constrained designs requiring two independent signal paths.

Part Context

This part belongs to the AD8610/AD8620 family of precision amplifiers utilizing XFCB technology. The AD8620 variant specifically provides dual channels within a single package, whereas the AD8610 offers single-channel options. Both share identical core electrical characteristics and are designed for high-performance analog signal processing tasks.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the same family. Verify that any alternative maintains the required JFET input architecture and low bias current specifications.
