AD8625AR-REEL7

Overview

The AD8625AR-REEL7 is a quad precision JFET input operational amplifier featuring true single-supply operation and rail-to-rail output. It operates on supply voltages from 5 V to 26 V (single) or ±2.5 V to ±13 V (dual). Key electrical parameters include a maximum offset voltage of 0.5 mV, typical supply current of 630 μA per amplifier, gain bandwidth product of 5 MHz, and slew rate of 5 V/μs. The device maintains stability with capacitive loads exceeding 500 pF.

Feature Summary

• Features true single-supply capability with rail-to-rail output swing for maximum dynamic range.
• Utilizes n-channel JFET input stage providing very low input bias current and high input impedance.
• Designed for unity-gain stability without phase reversal near 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 SOIC and TSSOP configurations. Confirm that the REEL7 designation corresponds to the intended tape and reel packaging format for automated assembly processes. Ensure environmental compliance requirements align with the component specifications.

Selection Notes

Select this component when low input bias current and precision are critical for single-supply applications. The quad configuration offers space efficiency compared to individual amplifiers. Consider the 5 MHz bandwidth and fast slew rate for applications requiring faster signal settling than older single-supply JFET amplifiers provide.

Part Context

This part belongs to the AD862x family of precision low-power single-supply JFET amplifiers manufactured by Analog Devices. The AD8625 specifically denotes the quad-channel variant within this series, distinguished from the dual-channel AD8626 and single-channel AD8627 models.

Replacement Considerations

Direct substitutes within the same family include the AD8626 and AD8627, provided channel count differences are acceptable. Verify pin compatibility and package dimensions before substitution.
