AD8625ARZ-REEL

Overview

The AD8625ARZ-REEL is a quad precision JFET input operational amplifier from the AD862x family, manufactured by Analog Devices Inc. It features true single-supply operation with a supply voltage range of 5 V to 26 V and dual-supply operation from ±2.5 V to ±13 V. The device offers rail-to-rail output capability, low supply current of less than 630 μA per amplifier, and a gain bandwidth product of 5 MHz. Key electrical specifications include a maximum offset voltage of 500 μV at 25°C and a maximum input bias current of 1 pA. The outputs remain stable with capacitive loads exceeding 500 pF.

Feature Summary

• Features true single-supply operation and rail-to-rail output swing for maximum dynamic range in low-voltage systems.
• Utilizes n-channel JFET input stage to provide very low input bias current and high input impedance.
• Maintains stability with capacitive loads greater than 500 pF without oscillation.
• Designed with no phase reversal when input signals approach the positive supply rail.

Applications

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

Procurement Notes

Verify the specific package suffix matches the required footprint, as the AD8625 is available in both SOIC and TSSOP configurations. Confirm that the REEL7 designation corresponds to the correct tape and reel quantity specified in the ordering guide. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when designing circuits requiring low power consumption alongside high DC precision. The quad configuration reduces board space compared to using individual single amplifiers. Consider the 5 MHz bandwidth for applications requiring faster settling times than older single-supply JFETs. Verify that the input common-mode voltage range accommodates signals extending slightly below the negative rail if operating in single-supply mode.

Part Context

This part belongs to the AD862x series of precision low-power single-supply JFET amplifiers. The AD8625 specifically contains four independent amplifiers within a single package, distinguishing it from the dual AD8626 and single AD8627 variants. All members of the family share identical electrical characteristics and pinouts, differing only in channel count and package options.

Replacement Considerations

Direct functional replacements within the same family include the AD8626 (dual) and AD8627 (single). For quad configurations, verify pin compatibility between SOIC and TSSOP packages if substituting based on package type rather than just function.
