The AD22100 is a temperature sensor produced by Analog Devices. It features high accuracy, good linearity, wide temperature range and wide application scenarios.
The AD22100 is a monolithic temperature sensor with on‑chip signal conditioning that provides a voltage output proportional to temperature and supply voltage. It is suited for HVAC, instrumentation, and automotive applications, operating over a –50 °C to +150 °C range with a single‑supply (+5 V) design.
Key features include a ratiometric transfer function, low quiescent current, short‑circuit tolerant output stage, and two package options (3‑lead TO‑92 and 8‑lead SOIC). The device offers minimal self‑heating, easy interfacing to ADCs, and detailed specifications for accuracy, linearity, and thermal performance.
| Operating Voltage | 4 V to 6.5 V |
|---|---|
| Operating Temperature Range | -50 °C to +150 °C |
| Nominal Output Voltage at 0 °C (V+ = 5 V) | 1.375 V |
| Nominal Output Voltage at +150 °C (V+ = 5 V) | 4.750 V |
| Transfer Function | Vout = (V+/5 V) × [1.375 V + 22.5 mV/°C × Ta] |
The device operates from 4 V up to 6.5 V.
At a 5 V supply the output ranges from 0.25 V at –50 °C to 4.75 V at +150 °C.
The device can safely source about 7 mA in a short‑circuit condition.
