PRODUCT FEATURES
Datasheet
General Description
The EMC1073 and EMC1074 are high accuracy, low
cost, System Management Bus (SMBus) temperature
sensors 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).
Applications
