AD8610ARM-REEL

Overview

The AD8610ARM-REEL is a precision, very low noise, low input bias current, wide bandwidth JFET operational amplifier manufactured by Analog Devices Inc. It features a maximum offset voltage of 100 μV and an input bias current of 10 pA maximum. 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 a gain bandwidth product of 25 MHz and a slew rate of 50 V/μs at ±5 V or 60 V/μs at ±13 V. Settling time to 0.01% is 600 ns. The component is housed in an 8-lead MSOP package and is fully specified over the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Features ultralow offset voltage and drift combined with very low input voltage and current noise for high precision applications.
• Maintains low input bias current across the entire operating temperature range without significant increase at elevated temperatures.
• Capable of driving large capacitive loads safely without external compensation while maintaining unconditional stability.
• Designed with no phase reversal characteristics when inputs are forced beyond the common-mode voltage range.

Applications

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

Procurement Notes

Verify that the ordering suffix ARMZ corresponds to the 8-lead MSOP package configuration as specified in the manufacturer's documentation. Confirm that the REEL7 designation indicates tape and reel packaging suitable for automated surface-mount assembly processes. Ensure compatibility with the required supply voltage range of ±5 V to ±13 V for the intended application environment.

Selection Notes

Select this component when design requirements demand high precision JFET input characteristics with minimal bias current drift over temperature. Consider its capability to drive heavy capacitive loads directly if interfacing with long cables or sample-and-hold circuits. Evaluate the 25 MHz gain bandwidth and 60 V/μs slew rate against signal frequency requirements to ensure adequate dynamic performance without additional compensation components.

Part Context

The AD8610 is part of the AD8610/AD8620 family of precision amplifiers utilizing the XFCB process technology. This manufacturing method employs dielectrically isolated N-channel JFETs and thin film resistors to achieve superior offset trimming and low noise performance. The AD8610 represents the single-channel version of this architecture, offering high output drive capabilities and stability comparable to bipolar amplifiers while retaining JFET input advantages.
