How to Interpret DS1847/DS1848 Temperature Readings

Abstract: The DS1847 and DS1848 have an on-chip direct-to-digital temperature sensor. The temperature is
stored in address locations E2h and E3h. This application note explains how to convert the digital temperature
data into a decimal degrees Celsius value.


Translating Temperatures from Hex to Decimal

The procedure for converting temperature values for the DS1847 and DS1848 begins with reading the hex
values stored in bytes E2h (the MSB of the tempe
