Analog Devices Temperature Sensor, Digital Output, Surface Mount, I2C, 0.1%, 16 Pins

The Analog Devices 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. Operating at 3.0 V, the average supply current is typically 210 μA.
