ADT7422 - Temperature Sensor

Description

The ADT7422 is a high accuracy, digital I2C temperature sensor designed to meet the clinical thermometry specification of the ASTM E1112 standards when soldered onto the final printed circuit board (PCB).

Features

  • Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered onto the final PCB ±0.1°C from 25°C to 50°C at 3.0 V ±0.25°C from.
  • 20°C to +105°C at 2.7 V to 3.3 V Ultralow temperature drift: 0.0073°C National Institute of Standards and Technology (NIST) traceable or equivalent Fast first temperature conversion at power-up of 6 ms Simple implementation No temperature calibration or correction required No linearity correction required Low power 140 µW typical at 3.0 V in.
