AD8610ARZ-REEL

Overview

The AD8610ARZ-REEL is a precision, very low noise, low input bias current, wide bandwidth JFET 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 or 60 V/μs at ±13 V supply. The device has a maximum input offset voltage of 100 μV and an input bias current of 10 pA maximum. It operates on dual supplies ranging from ±5 V to ±13 V with a typical supply current of 3.5 mA per amplifier. The component is housed in an 8-lead SOIC package and is specified for operation over an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Features ultralow offset voltage and drift achieved through thin film resistor trimming techniques.
• Maintains extremely low input bias currents across the entire operating temperature range.
• Capable of driving large capacitive loads without external compensation while remaining stable.
• Designed with no phase reversal 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 REEL corresponds to tape and reel packaging as specified for the MSOP variant, though this part uses SOIC. Confirm the specific grade (e.g., B grade) matches design requirements for offset voltage limits. Ensure the manufacturer is Analog Devices Inc. and check RoHS compliance status against current datasheet revisions before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high precision JFET input characteristics combined with wide bandwidth. It is suitable for driving high-performance ADC inputs and buffering DAC outputs due to its high output drive capability. Consider the extended temperature range and low power consumption benefits for portable or high-density systems where thermal management is critical.

Part Context

The AD8610 is part of the AD8610/AD8620 family of precision amplifiers. While the AD8620 is a dual-channel version, the AD8610 is a single-channel device. Both share identical electrical specifications and are manufactured using the XFCB process. The AD8610 is available in narrow 8-lead SOIC and tiny 8-lead MSOP packages, with the MSOP version exclusively available in tape and reel.

Replacement Considerations

The AD8620 is a dual-channel equivalent within the same family sharing identical electrical performance. Other precision JFET amplifiers may serve as functional replacements if pin compatibility and specific parameters like offset voltage and bandwidth meet the circuit requirements.

FAQ

Does the AD8610 require external compensation when driving capacitive loads?

No, the AD8610 can safely drive large capacitive loads, up to 10 nF with a ±5.0 V supply, without any external compensation.

What is the input overvoltage protection capability of the AD8610?

The AD8610 allows input voltages more than 5 V beyond either power supply rail when protected by a series resistor, such as 10 kΩ, which generates minimal additional offset voltage.
