The ADT7312 is a ±1°C accurate digital temperature sensor that operates over a very wide temperature range, −55°C to +175°C available in die form only. It contains an internal 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 ADT7312 is guaranteed to operate over supply voltages from 2.7 V to 5.5 V. At 3.6 V operation, the average supply current is typically 245 μA. The ADT7312 has a shutdown mode that powers down the device, resulting in a typical shutdown current of 2.5 μA at 3.6 V. The ADT7312 is rated for operation over the −55°C to +175°C temperature range.
The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The default critical temperature limit is 147°C. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT pin and the CT pin can operate in either comparator or interrupt mode.
