The ADT75ARM is a complete temperature monitoring system in 8-lead MSOP and SOIC packages. It contains a band gap temperature sensor and 12-bit Aanalog-to-digital converter (ADC) to monitor and digitize the temperature to a resolution of 0.0625°C. The ADT75ARM is pin and register compatible with the LM75 and AD7416.
The ADT75ARM is specified for operation at supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 200 μA.
The ADT75ARM offers a shutdown mode that powers down the device and this mode gives a shutdown current of typically 3 μA. The ADT75ARM is rated for operation over the –55°C to +125°C temperature range.
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.
