AD8627AKSZ-REEL7

Overview

The AD8627AKSZ-REEL7 is a precision JFET input operational amplifier manufactured by Analog Devices Inc. It features true single-supply operation with a voltage range of 5 V to 26 V, or dual supply operation from ±2.5 V to ±13 V. The device provides 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

• Features very low input bias current with a maximum specification of 1 pA.
• Provides rail-to-rail output swing for maximum dynamic range in single-supply systems.
• Maintains unity gain stability without phase reversal near the positive supply rail.
• Designed for low power consumption with a typical supply current of 630 µA.

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 REEL7 corresponds to tape and reel packaging as specified for SC70 packaged parts. Confirm the component meets the industrial temperature range requirements (-40°C to +85°C) for your specific application environment. Ensure the design accounts for the absolute maximum ratings regarding supply voltage and input overvoltage protection.

Selection Notes

Select this component when picoampere-level input bias currents are critical for minimizing errors in high-impedance source applications. The rail-to-rail output makes it suitable for buffering CMOS DACs and ASICs where full output swing is required. Consider the 5 MHz bandwidth and 5 V/µs slew rate for precision filtering applications requiring fast settling times.

Part Context

The AD8627 is part of the AD862x family of precision low-power single-supply JFET amplifiers. This series includes the AD8625 (quad), AD8626 (dual), and AD8627 (single). The AD8627 specifically is available in 5-lead SC70 and 8-lead SOIC packages. The SC70 variant is exclusively supplied in tape and reel format.

Replacement Considerations

Direct functional substitutes within the same package and pinout include other members of the AD862x family such as the AD8626 or AD8625, provided channel count differences are acceptable. Verify thermal resistance values if replacing with different package types like SOIC.
