AD8620BRZ-REEL7

Overview

The AD8620BRZ-REEL7 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 within a supply range of ±5 V to ±13 V and supports an extended industrial temperature range from -40°C to +125°C. It is housed in an 8-lead SOIC package.

Feature Summary

• JFET input architecture providing ultralow offset voltage and drift alongside very low input bias current across the entire operating temperature range.
• High-speed dynamic performance with a 25 MHz gain bandwidth product and fast settling time to 0.01% accuracy.
• Capable of driving large capacitive loads without external compensation while maintaining unconditional stability in all gain configurations.
• Designed with no phase reversal characteristics when inputs are forced beyond the common-mode voltage range.

Applications

• Photodiode amplifiers
• Automated test equipment (ATE) amplification and buffering
• Medical instrumentation including CAT, MRI, and ultrasound systems
• Fast precision filters and integrator circuits

Procurement Notes

Verify that the REEL7 suffix corresponds to tape and reel packaging rather than tube packaging. Confirm the BRZ variant meets RoHS compliance standards for your region. Ensure the SOIC_N package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when high precision and low noise are required for JFET input applications. It serves as a suitable alternative to bipolar amplifiers where low bias current is critical. Consider its wide supply voltage range and robust capacitive load driving capability for complex signal conditioning tasks.

Part Context

This part belongs to the AD8610/AD8620 family of precision amplifiers utilizing the XFCB process. While the AD8610 is available in MSOP packages, the AD8620 is specifically offered in the narrow 8-lead SOIC format. The series is designed for high-density systems requiring superior thermal management and low power consumption.
