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……
