AD8626ARZ-REEL7

Overview

The AD8626ARZ-REEL7 is a dual precision JFET input operational amplifier from Analog Devices, housed in an 8-lead SOIC package. It features true single-supply operation with a voltage range of 5 V to 26 V, or dual supplies of ±2.5 V to ±13 V. Key electrical specifications include a maximum offset voltage of 0.5 mV, a gain-bandwidth product of 5 MHz, and a slew rate of 5 V/µs. The device draws a typical supply current of 630 µA per amplifier and offers rail-to-rail output capability.

Feature Summary

• JFET input stage providing ultra-low input bias current for minimal signal loading
• Rail-to-rail output swing maximizing dynamic range in single-supply systems
• True single-supply operation allowing inputs to extend below the negative rail
• Unity gain stable design without phase reversal near positive supply rails

Applications

• Photodiode transimpedance amplification
• Precision active filters
• Line-powered and battery-powered instrumentation
• Automotive sensor signal conditioning

Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when sourcing. Confirm the R-8 suffix corresponds to the 8-lead SOIC package variant required for your PCB layout. Ensure the industrial temperature range specification aligns with your environmental operating conditions before finalizing procurement.

Selection Notes

Select this component for applications requiring low power consumption combined with high input impedance. The 5 MHz bandwidth supports precision filtering requirements. Verify that the 1 pA maximum input bias current meets the leakage constraints of your source impedance. Ensure the 8-lead SOIC footprint matches your assembly capabilities.

Part Context

This part belongs to the AD862x family of precision low-power single-supply JFET amplifiers. The AD8626 specifically provides two channels within a compact surface-mount package. It shares core performance characteristics with the AD8625 and AD8627 variants, differing primarily in channel count and available package options.

Replacement Considerations

Direct functional equivalents within the same family include the AD8625 and AD8627, subject to package compatibility.
