APPLICATION NOTE 237
Introduction of the DS1847 for Industrial Controls

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
