EMC1074

In Production

The EMC1073 and EMC1074 are high accuracy, low cost, System Management Bus (SMBus) temperature sensor with pin selectable SMBus addresses. Each device provides ±1° accuracy (max) for external diode temperatures and ±2°C accuracy (max) for the internal diode temperature. The EMC1073 monitors three temperature channels (two external and one internal). The EMC1074 monitors four temperature channels (three external and one internal).
