The ADT75 is a complete temperature monitoring system in 8-lead MSOP and SOIC packages. It contains a band gap temperature sensor and 12-bit 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 specified for operation at supply voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current is typically 300 μA. The ADT75 offers a shutdown mode that powers down the device and gives a shutdown current of typically 3 μA. The ADT75 is rated for operation over the –55°C to +125°C temperature range.

Three pins (A0, A1 and A2) are available for address selection. There is also an open-drain OS/ALERT output that becomes active when temperature exceeds a programmable limit. This pin can operate in either comparator or interrupt mode.
