The EMC1072 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor with pin selectable SMBus address.

The device provides ±1° accuracy (max) for external diode temperatures and ±2°C accuracy (max) for the internal diode temperature. The EMC1072 monitors two temperature channels (one external and one internal).
