AD8641AKSZ-REEL

Overview

The AD8641AKSZ-REEL7 is a low power, precision JFET input operational amplifier featuring rail-to-rail output. It operates from single supplies of 5 V to 26 V or dual supplies of ±2.5 V to ±13 V. Key electrical characteristics include a maximum supply current of 250 μA, an input bias current of 1 pA, and a maximum offset voltage of 750 μV. The device offers a gain bandwidth product of 3 MHz and a slew rate of 2 V/μs at 5 V. It is unity-gain stable with no phase reversal and remains stable with capacitive loads exceeding 500 pF.

Feature Summary

JFET input architecture providing extremely low input bias current
Rail-to-rail output capability for wide dynamic range
Unity-gain stability without phase reversal issues
Capacitive load stability exceeding 500 pF

Applications

Photodiode amplifiers
Precision current sensing
Line- or battery-powered instruments
ATE reference level drivers
Industrial controls

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the KS-5 package designation matches the intended footprint on the printed circuit board layout. Ensure the RoHS compliant status aligns with environmental regulations applicable to the manufacturing region.

Selection Notes

Select this component when low quiescent current and high input impedance are critical requirements. The rail-to-rail output allows for maximum signal swing in single-supply systems. Verify that the 3 MHz bandwidth meets the frequency response needs of the application. Consider the SC70 package dimensions if space constraints are a primary design factor.

Part Context

This part belongs to the AD864x family of precision amplifiers manufactured by Analog Devices. The AD8641 variant provides a single amplifier channel, whereas the AD8642 and AD8643 offer dual and quad configurations respectively. All variants share similar electrical specifications but differ in pin counts and package options to suit various integration densities.
