GENERAL DESCRIPTION
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 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 210 μA. The ADT7310 has a shutdown mode that powers down the device and offers a shutdown current of typically 2 μA. 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……
