AD8626ARMZ-REEL

Overview

The AD8626ARMZ-REEL is a dual precision JFET input operational amplifier from Analog Devices. It features true single-supply operation with a supply voltage range of 5 V to 26 V, or ±2.5 V to ±13 V in dual-supply configurations. The device offers rail-to-rail output capability and maintains stability with capacitive loads exceeding 500 pF. Key electrical specifications include a maximum offset voltage of 500 μV, a typical supply current of 630 μA per amplifier, and a gain-bandwidth product of 5 MHz. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

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

Applications

• Photodiode transimpedance amplification
• ATE reference level drivers
• Battery management systems
• Remote sensor signal conditioning including automotive sensors
• Precision active filters such as Sallen-Key topologies

Procurement Notes

Verify the RM suffix indicates the MSOP package configuration when ordering. Confirm that the REEL designation corresponds to tape and reel packaging rather than tube packaging. Ensure the component meets RoHS compliance requirements for your specific manufacturing process. Check datasheet revision F for the most recent electrical characteristics and application guidelines before finalizing procurement specifications.

Selection Notes

Select this component for circuits requiring low power consumption combined with high input impedance. The 5 MHz bandwidth supports precision filtering applications where low offset voltage is critical. Consider the rail-to-rail output feature for buffering CMOS DACs or ASICs in single-supply environments. Evaluate thermal dissipation if driving heavy loads, as junction temperature affects input bias current performance over the specified industrial temperature range.

Part Context

This part belongs to the AD862x family of precision low-power single-supply JFET amplifiers. The AD8626 specifically provides two channels in an 8-lead MSOP package. It shares architectural similarities with the AD8625 and AD8627 but differs in channel count and package availability. The family is designed for applications demanding picoampere-level input currents and low noise performance.

Replacement Considerations

Direct functional substitutes within the same series include the AD8625 and AD8627, though package and channel counts differ. Verify pin compatibility and electrical parameters against the original design requirements before substitution.
