AD8627ARZ-REEL7

Overview

The AD8627ARZ-REEL7 is a precision single-supply JFET input operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and operates on supply voltages ranging from 5 V to 26 V (single) or ±2.5 V to ±13 V (dual). The device offers a gain bandwidth product of 5 MHz, a maximum offset voltage of 0.5 mV at 25°C, and a typical supply current of 630 μA per amplifier. It is housed in an 8-lead SOIC package.

Feature Summary

• True single-supply operation with rail-to-rail output swing
• JFET input stage providing very low input bias current
• Unity gain stable with no phase reversal near the positive rail
• Capacitive load stability exceeding 500 pF

Applications

• Photodiode transimpedance amplification
• ATE reference level drivers
• Battery management systems
• Remote sensor signal conditioning including automotive sensors
• Precision filters

Procurement Notes

Verify that the ordering suffix ARZ corresponds to the 8-lead SOIC package variant rather than the SC70 option. Confirm the REEL7 designation indicates tape and reel packaging. Ensure the component meets industrial temperature range specifications (-40°C to +85°C) required for the target application environment.

Selection Notes

Select this component when picoampere-level input bias currents are critical for minimizing errors in high-impedance circuits. The rail-to-rail output allows for maximum dynamic range in single-supply systems. Verify that the 5 MHz bandwidth and 5 V/μs slew rate meet the signal frequency requirements without introducing significant settling time delays.

Part Context

This part belongs to the AD862x family of precision low-power amplifiers. While the AD8625 is a quad configuration and the AD8626 is a dual, the AD8627 is a single-channel amplifier. All variants share identical electrical characteristics but differ in pin counts and package options such as TSSOP, MSOP, and SOIC.

Replacement Considerations
