Product details

It measures its own die temperature over a calibrated local range of 0°C to 100°C, while the device itself can survive and operate from -50°C to 150°C.

Package and mounting — through-hole convenience

Housed in a TO-92-3 through-hole package, the AD22100KTZ suits hand-assembly, breadboard prototyping, or retrofit into legacy boards that lack SMD pads. The three leads are V+, GND, and Vout — no external components needed for basic operation.

ADI lists the AD22100KTZ as Active (current production). No last-time-buy notice, no end-of-life risk for ongoing designs. No direct second-source from another manufacturer, but the AD22100 family shares the same pinout and scaling — the AD22100STZ is the same die in a surface-mount SOIC-8 if your board later migrates to SMD.

Frequently asked questions

What is the accuracy of AD22100KTZ?

Accuracy is ±2°C at 25°C test condition. The local sensing range is 0°C to 100°C.

When sourcing AD22100KTZ, what is the closest functional alternative?

The AD22100STZ is the surface-mount (SOIC-8) version of the same die, with identical 22.5 mV/°C scaling and ±2°C accuracy, but a wider local sensing range of -50°C to 150°C. Pinout differs — verify before swapping.
