Abstract: This application note introduces the DS1847 and DS1848, dual digital temperature-controlled variable resistors, to the industrial controls market. By temperature compensating the resistors, the resistors can either remain at a specific resistance or vary over temperature by programming a unique resistor value every 2°C. The DS1847 can also be used to control voltage or current. The DS1847 and DS1848 are identical except the DS1848 includes additional user programmable EEPROM. In this application note, DS1847 will refer to the DS1847 and DS1848.
