AD8610BRZ-REEL7

Overview

The AD8610BRZ-REEL7 is a single-channel precision JFET operational amplifier manufactured by Analog Devices. It features a gain bandwidth product of 25 MHz, a slew rate of 50 V/µs at ±5 V and 60 V/µs at ±13 V, and an input offset voltage maximum of 100 µV. The device operates on dual supplies ranging from ±5 V to ±13 V with a supply current of 3.5 mA per amplifier. It provides low noise performance with a voltage noise density of 6 nV/√Hz and maintains low input bias current up to 10 pA. The component 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 full operating temperature range.
• High-speed dynamic performance characterized by wide bandwidth and fast settling time to 0.01% accuracy.
• Capable of driving large capacitive loads exceeding 1000 pF without external compensation while maintaining unity gain stability.
• Input overvoltage protection allows operation beyond the supply rails without phase reversal or damage.

Applications

• Photodiode amplifiers
• Automated test equipment (ATE)
• Instrumentation and sensor controls
• High-performance filters
• Fast precision integrators

Procurement Notes

Verify the specific B-grade offset voltage classification against project requirements. Confirm that the REEL7 suffix indicates tape and reel packaging suitable for automated surface-mount assembly. Ensure the SOIC-8 package dimensions match the PCB footprint design. Validate that the extended industrial temperature range meets environmental specifications.

Selection Notes

Select this component when high precision and low noise are critical for signal integrity. The JFET input stage is optimal for high-impedance sources requiring minimal loading. Consider the wide bandwidth and slew rate for applications involving fast transient signals. Evaluate the output drive capability for driving heavy loads or long cables directly.

Part Context

This part belongs to the AD8610/AD8620 family of precision amplifiers utilizing the XFCB process. The AD8610 represents the single-channel variant, whereas the AD8620 offers dual channels. Both share identical electrical characteristics and pinouts, differing only in channel count within the same 8-lead package.

Replacement Considerations

The AD8610ARZ serves as the standard grade alternative with slightly higher offset voltage specifications. Verify compatibility if transitioning between different package styles such as MSOP versus SOIC.

FAQ

Does the AD8610 exhibit phase reversal when inputs exceed the common-mode range?

No, the device is designed to prevent phase reversal even when one or both inputs are forced beyond the input common-mode voltage range.

What is the maximum capacitive load the AD8610 can drive stably?

The amplifier is stable with capacitive loads well in excess of 1000 pF in noninverting unity gain configurations.
