AD8610ARM-R2

Overview

The AD8610ARM-R2 is a single-channel, precision JFET input operational amplifier manufactured by Analog Devices. It features a gain bandwidth product of 25 MHz and a slew rate of 50 V/μs at ±5 V supply. The device offers low noise density of 6 nV/√Hz and maximum offset voltage of 100 μV. Operating on dual supplies from ±5 V to ±13 V, it provides high output drive capability with short-circuit protection. 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 extremely low input bias current and very low input offset voltage drift.
• Capable of driving large capacitive loads 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 amplification circuits
• Automated test equipment (ATE) signal conditioning
• Medical instrumentation including CAT, MRI, and ultrasound systems

Procurement Notes

Verify the specific suffix 'R2' against official documentation to confirm tape and reel packaging requirements. Ensure the selected grade matches the required offset voltage specifications. Confirm that the MSOP package dimensions align with the target PCB footprint. Validate that the operating temperature range meets system environmental constraints.

Selection Notes

Select this component for applications requiring high precision combined with wide bandwidth and fast settling times. The low input bias current makes it suitable for high-impedance sensor interfaces. Consider the power consumption relative to bipolar alternatives like the OPA627 for portable or thermally constrained designs.

Part Context

This part belongs to the AD8610/AD8620 family of precision amplifiers utilizing the XFCB process. The AD8610 represents the single-channel version, while the AD8620 is the dual-channel variant. Both share identical electrical characteristics and pinouts, differing only in channel count and package availability.

Replacement Considerations

The OPA627 is a comparable precision amplifier often used in similar applications. Designers should note differences in slew rate symmetry, capacitive load driving capabilities, and power consumption when substituting between these devices.
