AD8627AR-REEL

Overview

The AD8627AR-REEL is a precision single-supply JFET input amplifier manufactured by Analog Devices Inc. It operates on supply voltages ranging 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, a maximum input bias current of 1 pA, and a gain bandwidth product of 5 MHz. The device features rail-to-rail output capability, unity gain stability, and low power consumption with a typical supply current of 630 μA per amplifier.

Feature Summary

• Features true single-supply operation with an input voltage range extending below the negative rail.
• Provides rail-to-rail output swing for maximum dynamic range in single-supply systems.
• Maintains stability with capacitive loads exceeding 500 pF without phase reversal near the positive rail.

Applications

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

Procurement Notes

Verify that the ordering suffix AR-REEL corresponds to the 8-lead SOIC package configuration as specified in the official documentation. Confirm that the component meets industrial temperature range requirements (-40°C to +85°C) for your specific application environment. Ensure proper handling precautions are taken due to the high impedance JFET input stage sensitivity to electrostatic discharge.

Selection Notes

Select this component when low input bias current and high input impedance are required for precision applications. The rail-to-rail output makes it suitable for buffering CMOS DACs and ASICs where full output swing is necessary. Consider its 5 MHz bandwidth and low offset voltage for use in precision filters and instrumentation circuits requiring high DC accuracy.

Part Context

The AD8627 is part of the AD862x family of precision JFET input amplifiers, which also includes the dual-channel AD8626 and quad-channel AD8625. This family shares common characteristics such as low power consumption, rail-to-rail outputs, and true single-supply operation. The AD8627 specifically provides a single amplifier channel in surface-mount packages.

Replacement Considerations

Direct replacements within the same family include the AD8626 (dual channel) and AD8625 (quad channel), provided pin compatibility and channel count requirements are met. Verify package dimensions and pinout configurations before substitution.
