Digital temperature sensor meets clinical thermometry specification standards

01-05-2020 | Analog Devices | Test & Measurement

Analog Devices ADT7422 Digital Temperature Sensor is intended to meet the ASTM E1112 standard of clinical thermometry specification.


This temperature sensor functions with 210µA of the average supply current at 3V. The sensor gives a 16-bit temperature, 0.0078C resolution, and up to ±0.1C accuracy without calibration after the PCB soldering process. The sensor allows shutdown mode to power down the device and gives a shutdown current of 2µA at 3V input voltage.


This sensor is employed in applications such as Vital Signs Monitoring, medical equipment, thermocouple cold junction compensation, and laser diode temperature control.
