Product details

Programmable trip point — setting the guard band

The AD22105ARZ: Hysteresis is not selectable on this variant, so the output clears when the die cools approximately 4°C below the trip threshold — factor this into the thermal management loop for fan or alarm control.

Package and board-fit note

Housed in an 8-lead SOIC (narrow-body) package, the AD22105ARZ mounts on the PCB with the exposed die paddle soldered to the ground plane for thermal coupling — the sensor measures its own die temperature, so the trace copper area under the package sets the thermal time constant. Supplied in tube packaging, this is the standard pick-and-place quantity for prototype and low-volume builds; the sibling AD22105ARZ-REEL7 is the same die in tape-and-reel for automated assembly lines.

Frequently asked questions

Where can I buy AD22105ARZ and how do I get a price?

The AD22105ARZ is sourced to order against an RFQ through independent and authorized distribution channels.

What is the closest functional second-source to AD22105ARZ?

The AD22105ARZ-REEL7 is electrically identical — same die, same ±2°C accuracy, same Active High open-collector output — differing only in packaging (tape-and-reel vs tube). It drops into the same PCB footprint without rewiring or requalification.
