AD8627ARZ

Overview

The AD8627ARZ is a precision, low-power, single-supply JFET input operational amplifier manufactured by Analog Devices. It features rail-to-rail output capability and operates from a single supply of 5 V to 26 V or dual supplies of ±2.5 V to ±13 V. The device offers a gain bandwidth product of 5 MHz, a slew rate of 5 V/µs, and a maximum input bias current of 1 pA. It is housed in an 8-lead SOIC package.

Feature Summary

• JFET input stage providing ultra-low input bias current
• Rail-to-rail output swing for maximum dynamic range
• True single-supply operation with extended common-mode range
• Unity gain stable without phase reversal near positive rail

Applications

• Photodiode transimpedance amplifiers
• Precision filters
• Automotive sensors
• Output buffers for DACs

Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the 8-lead SOIC package configuration required for your design. Confirm that the component meets RoHS compliance standards as specified in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when picoampere-level input currents are critical for signal integrity. The rail-to-rail output allows compatibility with CMOS logic levels in single-supply systems. Ensure the application does not require shutdown functionality, as this model lacks that feature.

Part Context

This part belongs to the AD862x family of precision amplifiers, which includes the quad-channel AD8625 and dual-channel AD8626. While sharing identical electrical specifications and core architecture, the AD8627 provides a single amplifier channel in a compact surface-mount package suitable for space-constrained designs.

Replacement Considerations

The AD8626ARZ serves as a functional replacement if dual channels are available and one remains unused. Verify pinout compatibility between the SOIC packages to ensure direct interchangeability without PCB redesign.
