AD8625ARZ-REEL7

Overview

The AD8625ARZ-REEL7 is a quad precision JFET input 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. Input bias current is typically 1 pA. The device maintains stability with capacitive loads exceeding 500 pF and operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Features true single-supply capability with rail-to-rail output swing for maximum dynamic range.
• Utilizes n-channel JFET input stage providing extremely low input bias current and high input impedance.
• Maintains unity gain stability without phase reversal when input signals approach the positive supply rail.
• Designed for stable operation with capacitive loads exceeding 500 pF.

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 against the datasheet ordering guide to ensure correct pinout and physical dimensions. Confirm that the REEL7 designation matches the required tape and reel packaging specifications for automated assembly processes. Cross-reference the manufacturer part number with official Analog Devices documentation to validate revision levels and compliance status before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low power consumption combined with high DC precision in single-supply environments. The wide input common-mode voltage range extending below the negative rail allows for handling signals near ground potential. Ensure the system design accounts for the 5 MHz bandwidth and 5 V/μs slew rate to meet signal fidelity requirements.

Part Context

This device belongs to the AD862x family of precision low-power single-supply JFET amplifiers manufactured by Analog Devices. The AD8625 specifically integrates four independent amplifiers into a single package, offering a compact solution for multi-channel signal processing tasks compared to dual or single-channel variants within the same series.

Replacement Considerations

Consult the official datasheet ordering guide for verified substitute part numbers within the AD862x family. Ensure any replacement maintains compatibility with the 14-pin SOIC package and meets the specified electrical characteristics for the intended application environment.
