Analog Devices AD22100 Voltage Output Temperature Sensor Datasheet
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.
