AD8627AKSZ-REEL

Overview

The AD8627AKSZ-REEL is a precision JFET input amplifier in a 5-lead SC-70 package. It supports single-supply operation from 5 V to 26 V and dual-supply operation from ±2.5 V to ±13 V. The device features rail-to-rail output, low supply current of 630 μA/amp typ, and unity gain stability. Key electrical parameters include a maximum offset voltage of 500 μV, maximum input bias current of 1 pA, and a gain bandwidth product of 5 MHz. It operates over an industrial temperature range of −40°C to +85°C.

Feature Summary

• True single-supply capability with input voltage range extending below the negative rail
• Rail-to-rail output stage providing maximum dynamic range
• Low input bias current utilizing n-channel JFETs for high impedance input
• 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
• Precision filters

Procurement Notes

Verify that the ordering suffix KS indicates the 5-lead SC-70 surface-mount package configuration. Confirm the REEL designation corresponds to tape and reel packaging as specified for this package type. Ensure the component matches the Analog Devices AD862x series specifications regarding supply voltage ranges and operating temperature limits before integration.

Selection Notes

Select this component when picoamp-level input bias currents are required alongside true single-supply operation. The rail-to-rail output allows buffering CMOS DACs and ASICs effectively. Consider the 5 MHz bandwidth and low offset voltage for precision filtering applications. Verify that the SC-70 package dimensions fit the available PCB space constraints.

Part Context

The AD8627 is part of the AD862x family of precision low-power single-supply JFET amplifiers manufactured by Analog Devices. This family includes the AD8625 and AD8626 variants which offer different channel counts and package options such as SOIC and MSOP. The AD8627 specifically provides a single-channel solution optimized for compact designs requiring high precision and low power consumption.
