EMC1053 1C Triple Temperature Sensor with Resistance Error Correction & Hotter of Two Zones Datasheet PRODUCT FEATURES General Description Features Supports two External Temperature Diodes The EMC1053 is a System Management Bus (SMBus) 1C Accuracy (40C to 80C) temperature sensor that monitors three temperature 0.125C Resolution zones, one internal diode and two externally connected Ideality Factor Configuration diodes, for PC and embedded environments. The Accepts 2200pF Cap Across External Diodes for Noise EMC1053 includes resistance error correction and Suppression ideality factor configuration to eliminate major sources of Optional Resistive Error Correction on External Diode 2 1 Resistance Error Correction (up to 100 Ohms) temperature measurement error. Selectable Beta Compensation for Substrate Diodes An added feature to the EMC1053 is a function that Internal Temperature Diode automatically compares the two external temperature 3C Accuracy (0C to 85C) zones and reports the hotter of the two temperatures. 0.125C Resolution Selectable conversion rates and standby mode support Low Power Operation low-power operation. The temperature measurement 4uA Standby Current ranges support two data ranges (and formats), -64C to 3.0V to 3.6V Supply +127C and -64C to +191C.
