The ADT75 series 12-bit Digital Temperature Monitoring System containing a band gap temperature sensor and a 12-bit analogue-to-digital converter (ADC) to monitor and digitize the temperature to a resolution of 0.0625°C. The ADT75 is pin and register compatible with the LM75 and AD7416. The ADT75 is a shutdown mode that powers down the device and this mode gives a shutdown current of typically 3µA. The A0, A1 and A2 pins are available for address selection. The OS/ALERT pin is an open-drain output that becomes active when temperature exceeds a programmable limit. The OS/ALERT pin can operate in either comparator or interrupt mode. On-chip temperature sensor allows an accurate measurement of the ambient temperature.

• Over-temperature indicator
• Shutdown mode for low power consumption
• Power consumption 79µW typically at 3.3V
