AD8641AKSZ-R2

Overview

The AD8641AKSZ-R2 is a single-channel, low-power precision JFET input amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and operates within an extended industrial temperature range of −40°C to +125°C. The device is housed in a 5-lead Thin Shrink Small Outline Transistor (KS-5) package. Key electrical specifications include a maximum supply current of 250 µA, a maximum input bias current of 1 pA, and a maximum offset voltage of 750 µV. It supports single-supply operation from 5 V to 26 V or dual-supply operation from ±2.5 V to ±13 V.

Feature Summary

Extremely low input bias current suitable for high-impedance signal sources
Rail-to-rail output swing capability for maximizing dynamic range
Unity-gain stable with no phase reversal upon overdrive
Capacitive load stability exceeding 500 pF

Applications

Photodiode amplifiers
Precision current sensing
Line- or battery-powered instruments
Medical instrumentation
ATE reference level drivers

Procurement Notes

Verify the specific ordering suffix R2 indicates tape-and-reel packaging when sourcing components. Confirm that the Z designation confirms RoHS compliance status. Ensure the supplier provides documentation verifying the component meets the specified -40°C to +125°C operating temperature range requirements for your application environment.

Selection Notes

Select this component for applications requiring minimal power consumption alongside high input impedance. The KS-5 package is appropriate for space-constrained designs. Consider the AD8642 or AD8643 if multiple channels are required on a single board. Verify that the 3 MHz gain bandwidth product meets the frequency response needs of the target circuit.

Part Context

This part belongs to the AD864x family of low-power, precision JFET amplifiers. The family includes the AD8641 (single channel), AD8642 (dual channel), and AD8643 (quad channel). All variants share similar electrical characteristics regarding bias current, offset voltage, and power consumption, differing primarily in channel count and available package options.
