AD8610ARZ-REEL7

Overview

The AD8610ARZ-REEL7 is a single-channel, precision JFET input operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 25 MHz and a slew rate of 50 V/μs at ±5 V supply. The device exhibits a maximum offset voltage of 100 μV and an input bias current of 10 pA maximum. Operating on dual supplies from ±5 V to ±13 V, it delivers a supply current of 3.0 mA per amplifier. The component is housed in an 8-lead SOIC package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• JFET input architecture providing ultralow offset voltage and drift alongside very low input voltage and current noise across the entire operating temperature range.
• High-speed dynamic performance characterized by fast settling times and high output drive capability suitable for driving capacitive loads exceeding 1000 pF without external compensation.
• Unconditional stability with no phase reversal when inputs are forced beyond the common-mode voltage range, ensuring reliable operation in servo systems.

Applications

• Photodiode amplifiers
• Automated test equipment (ATE)
• Medical instrumentation including CAT, MRI, and ultrasound systems
• Fast precision integrators and high-performance filters

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to tape and reel packaging as specified for the 8-lead MSOP variant, though this part uses SOIC. Confirm the specific grade (e.g., AD8610B) matches the required offset voltage specifications. Ensure the manufacturer is Analog Devices Inc. and check RoHS compliance status before finalizing procurement.

Selection Notes

Select this component for applications requiring high precision combined with wide bandwidth and low noise. It is ideal for buffering DAC outputs or driving high-performance ADC inputs due to its high output drive and fast settling time. Consider the low input bias current for high-impedance sensor interfaces where leakage currents must be minimized.

Part Context

The AD8610 is part of the AD8610/AD8620 family of precision, very low noise, low input bias current, wide bandwidth JFET operational amplifiers. While the AD8620 offers dual channels, the AD8610 provides a single channel configuration. Both share identical electrical characteristics and are manufactured using the XFCB process for superior performance.

Replacement Considerations

The OPA627 is referenced in datasheet comparisons; however, the AD8610 offers significantly higher slew rates and better capacitive load driving capabilities. Verify pinout compatibility if substituting other single-channel JFET op-amps, noting the AD8610's specific null pins for offset adjustment.

FAQ

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

No, the AD8610 is designed to prevent phase reversal even when one or both inputs are forced beyond their input common-mode voltage range.

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

The AD8610 is stable with capacitive loads well in excess of 1 nF and can safely drive up to 10 nF when operating with a ±5.0 V supply without external compensation.
