AD8610AR-REEL

Overview

The AD8610AR-REEL is a precision, very low noise, JFET input 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 typical supply current of 3.0 mA per amplifier. It provides a gain bandwidth product of 25 MHz and a slew rate of up to 60 V/μs. The component is housed in an 8-lead MSOP package and is specified for operation across the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• JFET input architecture providing ultralow input bias current and high input impedance
• Very low input voltage noise density and low offset voltage drift
• Capable of driving large capacitive loads without external compensation
• Unconditionally stable with no phase reversal when inputs exceed common-mode range

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required package type, as the AD8610 is available in both SOIC and MSOP configurations. Confirm the specific grade if lower offset voltage is required, as standard specifications list a maximum of 100 μV. Ensure the reel packaging aligns with automated assembly requirements. Cross-reference the datasheet revision to confirm parameter consistency.

Selection Notes

Select this component for applications requiring high precision combined with wide bandwidth and low noise. It is suitable for buffering DAC outputs or driving ADC inputs due to its high output drive capability. Consider the power consumption relative to bipolar alternatives like the OPA627 for portable designs. Verify PCB layout practices to minimize leakage currents given the ultra-low bias current specification.

Part Context

The AD8610 belongs to the AD8610/AD8620 family of precision amplifiers utilizing Analog Devices' XFCB process. This technology combines dielectrically isolated transistors with N-channel JFET input stages and thin-film resistors. The series is designed to offer superior speed and bandwidth while maintaining low power consumption compared to traditional JFET amplifiers.

Replacement Considerations

The AD8610BRZ is a higher precision variant within the same family offering reduced offset voltage. The AD8620 is the dual-channel equivalent of the AD8610. Designers may also consider the OPA627 for comparison, though the AD8610 offers lower power consumption and better capacitive load driving capabilities.
