ADT7420UCPZ-R2

The ADT7420UCPZ-R2 is a high accuracy Digital Temperature Sensor offering breakthrough performance over a wide industrial range, with an internal band gap reference, a temperature sensor and a 16-bit ADC to monitor and digitize the temperature to 0.0078°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). The ADC resolution is user programmable mode that can be changed through the serial interface. The ADT7420 has a shutdown mode that powers down the device and offers a shutdown current of typically 2.0 µA at 3.3 V. Pin A0 and Pin A1 are available for address selection, giving the ADT7420 four possible I?C addresses. 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. The INT pin and CT pin can operate in comparator and interrupt event modes.
