ADT7422 Datasheet Temperature Sensor

Manufacturer: Analog Devices

Overview: Data Sheet ±0.1°C Accuracy, 16-Bit, Digital I2C Temperature Sensor for VSM.

General 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).

The ADT7422 contains an internal band gap reference, a temperature sensor, and a precision analog-to-digital converter (ADC).

The ADT7422 provides a 16-bit temperature result with a resolution of 0.0078°C and an accuracy of up to ±0.1°C across the temperature range of 25°C to 50°C without the need for calibration after the PCB soldering process.

Key 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.
