How to Interpret DS1854, DS1857, and DS1858 Temperature and
Voltage Readings
Abstract: The DS1854, DS1857, and DS1858 monitor VCC, ambient temperature, and external analog inputs.
This application note explains how to interpret the values stored in the Main Device SRAM and translate them
into temperature and voltages. A review of 2's complement conversion is also covered.
Translating Temperature from Binary to Decimal
The procedure for converting temperature values for the DS1854/57/58 begins with reading the values stored in
bytes 60h (MSB o……
