ADI ADT75ARZ-REEL

The ADT75 is a complete temperature monitoring system in 8-lead MSOP and SOIC packages. It contains a band gap temperature sensor and a 12-bit analog-to-digital converter (ADC) to monitor and digitize the temperature to a resolution of 0.0625℃. The ADT75 is pin and register compatible with the LM75 and AD7416. The ADT75 is guaranteed to operate at supply voltages from 2.7V to 5.5V. Operating at 3.3V, the average supply current is typically 200μA. The ADT75 offers a shutdown mode that powers down the device, and this mode gives a shutdown current of typically 3μA. The ADT75 is rated for operation over the -55℃ to +125℃ 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.
