Product Introduction
The ADT7310 is a high accuracy digital temperature sensor in a narrow SOIC package. It contains a band gap temperature reference and a 13-bit ADC to monitor and digitize the temperature to a 0.0625°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). This can be changed to 16 bits (0.0078°C) by setting Bit 7 in the configuration register (Register Address 0x01).
The ADT7310 is guaranteed to operate over supply voltages from 2.7V to 5.5V. Operating at 3.3V, the average supply current is typically 210μA. The ADT7310 has a shutdown mode that powers down the device and offers a shutdown current of typically 2μA. The ADT7310 is rated for operation over the -55°C to +150°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 and CT pins can operate in either comparator or interrupt mode.
