AD22100 is a temperature sensor from Analog Devices. It has a temperature range of 200°C, an accuracy better than ±2% of full scale, a linearity better than ±1% of full scale, a temperature coefficient of 22.5 mV/°C, and an output proportional to temperature × V+. It can be operated in a single-supply mode, supports reverse voltage protection, and has minimal self-heating and a high-level, low-impedance output. It is ideal for use in HVAC systems, system temperature compensation, board-level temperature sensing, and electronic thermostats.
The AD22100 is a monolithic ratiometric temperature sensor with on‑chip signal conditioning. It operates from –50 °C to +150 °C and provides a voltage output proportional to temperature and supply voltage, simplifying interfacing to ADCs.

| Operating Temperature Range | –50 °C to +150 °C |
|---|---|
| Quiescent Current | ≈ 500 µA |
| Nominal Output Voltage at 0 °C | 1.375 V (V+ =5 V) |
| Temperature Coefficient | 22.5 mV/°C |
The AD22100 operates from –50 °C to +150 °C.
The short‑circuit current limit is about 7 mA, but keeping the load current below 1 mA gives the best accuracy.
