ANALOG DEVICES ADT7422CCPZ-RL7

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). It contains an internal band gap reference, a temperature sensor, and a precision analogue-to-digital converter. The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. Application includes vital signs monitoring, medical equipment, resistance temperature detector and thermistor replacement, food transportation and storage, thermocouple cold junction compensation, environmental monitoring and heating, ventilation, and air conditioning, laser diode temperature control.
