The ADT7320 is a high accuracy digital temperature sensor that offers breakthrough performance over a wide industrial temperaturerange, housed in a 4 mm × 4 mm LFCSP package. It contains aninternal band gap reference, a temperature sensor, and a 16-bit analog-to-digital converter (ADC) to monitor and digitize the temperature to a resolution of 0.0078°C. The ADC resolution, by default, is set to 13 bits (0.0625°C). The ADC resolution is a user programmable mode that can be changed through the serial interface.
The ADT7320 is guaranteed to operate over supply voltages from2.7 V to 5.5 V. Operating at 3.3 V, the average supply current istypically 210 μA. The ADT7320 has a shutdown mode that powers down the device and offers a shutdown current of typically 2.0 μA at 3.3 V. The ADT7320 is rated for operation over the −40°C to +150°C temperature range.
The CT pin is an open-drain output that becomes active when thetemperature 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 pinand CT pin can operate in either comparator or interrupt mode.
