Product details

The AD22103KTZ is an analog-output temperature sensor from Analog Devices that delivers a linear voltage proportional to temperature at 28 mV/°C. The sensing range is 0°C to 100°C. The through-hole TO-92-3 package is breadboard-friendly.

Accuracy over the range — ±2°C at 25°C, ±2.5°C worst-case

The datasheet specifies ±2°C accuracy at 25°C and ±2.5°C over the full 0°C to 100°C span. That is a single-point trimmed sensor with no external calibration required. For a BOM decision: if your system needs better than ±2°C across the band, you either add a software lookup correction or move to a higher-grade digital sensor. For simple over-temperature alarms or trend monitoring, this accuracy is adequate and saves the cost of a reference resistor network.

For a BOM freeze, this is a low-risk line item — no imminent obsolescence, no lead-free transition issues. The TO-92-3 package is a mature, stable process that has been in production for decades.

Frequently asked questions

What is the accuracy of AD22103KTZ over the range?

Accuracy is ±2°C at 25°C and ±2.5°C over the full 0°C to 100°C operating range.

What is the equivalent part to AD22103KTZ?

The closest functional equivalent is the AD22103KRZ, which shares the same 28 mV/°C scaling, ±2°C (±2.5°C) accuracy, and 2.7 V supply, but in a surface-mount SOIC-8 package instead of through-hole TO-92-3. The AD22100KTZ is a through-hole sibling with a 22.5 mV/°C output and a wider -50°C to 150°C range, but requires a 4.0 V supply.

Can I buy AD22103KTZ in bulk?

Yes, this part is supplied in Bulk packaging. For volume purchases, submit an RFQ for pricing and lead time.
