AD8610ARMZ-REEL

Overview

The AD8610ARMZ-REEL is a precision, very low noise, low input bias current, wide bandwidth JFET operational amplifier manufactured by Analog Devices Inc. It features ultralow offset voltage and drift, very low input voltage and current noise, and wide bandwidth. The device operates with dual supplies from ±5 V to ±13 V and is stable with capacitive loads over 1000 pF in noninverting unity gain configurations. It offers fast settling times of 600 ns to 0.01% and high output drive capabilities, making it suitable for driving high-performance ADC inputs and buffering DAC converter outputs.

Feature Summary

• Features extremely low input bias current that remains low across the entire operating temperature range, unlike many competitive JFET amplifiers.
• Provides excellent capacitive load driving capability, remaining stable with large capacitive loads without external compensation.
• Designed with no phase reversal when inputs are forced beyond the common-mode voltage range, preventing lockup in servo systems.
• Includes input overvoltage protection allowing differential voltages equal to the supply voltage without damage.

Applications

• Photodiode amplifiers
• Automated Test Equipment (ATE)
• Instrumentation and sensors
• High performance filters
• Fast precision integrators

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the AD8610 is available in both 8-lead MSOP and 8-lead SOIC packages. Confirm that the REEL designation corresponds to tape and reel packaging, which is standard for the MSOP variant. Ensure the component grade meets the required offset voltage specifications for your application before procurement.

Selection Notes

Select this component for applications requiring high precision JFET input characteristics with minimal noise and bias current. Consider its wide bandwidth and fast settling time for high-speed signal processing tasks. Evaluate the power consumption benefits compared to bipolar alternatives for portable or high-density systems. Verify compatibility with the intended supply voltage range and capacitive load requirements.

Part Context

The AD8610 is part of the AD8610/AD8620 family of precision JFET operational amplifiers. It is manufactured using the XFCB process, which combines dielectrically isolated transistors with N-channel JFET technology. This family is designed for high precision applications, offering superior performance in terms of offset voltage, drift, and noise compared to standard JFET amplifiers.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. When evaluating alternatives, ensure comparable input bias current, offset voltage, and bandwidth specifications are met. Verify that any replacement maintains stability with similar capacitive loads and operates within the same supply voltage range.

FAQ

Does the AD8610 suffer from phase reversal?

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

How does the input bias current behave at elevated temperatures?

Unlike many JFET amplifiers, the AD8610 maintains very low input bias currents even at elevated temperatures, typically less than 200 pA at 85°C.

Can the AD8610 drive large capacitive loads?

Yes, the AD8610 can safely drive large capacitive loads, up to 10 nF with a ±5.0 V supply, without requiring external compensation.
