AD8610AR

Overview

The AD8610AR is a single-channel, precision JFET input 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, increasing to 60 V/μs at ±13 V. The device exhibits a maximum input offset voltage of 100 μV and an input bias current of 10 pA. Operating on dual supplies ranging from ±5 V to ±13 V, it provides high output drive capability with short-circuit protection. The component is housed in an 8-lead SOIC package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• JFET input architecture providing ultralow offset voltage and drift alongside very low input bias current across the full operating temperature range.
• Fast settling time of 600 ns to 0.01% accuracy combined with high slew rates for dynamic signal processing.
• Unconditional stability with capacitive loads exceeding 1 nF without external compensation.
• No phase reversal when inputs are forced beyond the common-mode voltage range.

Applications

• Photodiode amplifiers
• Automated test equipment (ATE)
• Instrumentation and sensor controls
• High-performance filters
• Fast precision integrators

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the selected variant matches the required thermal resistance and pin configuration for the target PCB layout. Cross-reference the revision history to confirm electrical parameter tolerances align with design requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring high DC precision combined with wide bandwidth and low noise. The JFET input stage is suitable for high-impedance sources where bias current must be minimized. Consider the extended temperature range and robust capacitive load driving capabilities for demanding industrial or medical environments.

Part Context

The AD8610 belongs to the AD8610/AD8620 family of precision amplifiers utilizing the XFCB process. This technology combines dielectrically isolated transistors with N-channel JFETs and thin-film resistors to achieve high speed and low power consumption. The AD8610 represents the single-channel version of this series, offering performance comparable to bipolar amplifiers while maintaining JFET input characteristics.

Replacement Considerations

The AD8610BRZ is a verified substitute within the same family, offering identical functionality in a tube package rather than tape and reel. Both variants share the same electrical specifications and pinout compatibility.

FAQ

Does the AD8610 require external compensation for capacitive loads?

No, the AD8610 is unconditionally stable with capacitive loads well in excess of 1 nF and does not require external compensation components.

What is the input overvoltage protection capability?

The device can withstand differential input voltages equal to the supply voltage without damage. For common-mode overvoltages exceeding the supply rails, a series resistor is recommended to limit substrate current.
