DS1867-100

The DS1867 Dual Digital Potentiometer with EEPROM is the nonvolatile version of the popular DS1267 Dual Digital Potentiometer.
The DS1867 consists of two digitally controlled potentiometers having 256-position wiper settings. Wiper position is maintained in the absence of power through the use of EEPROM memory cell arrays. Communication and control of the device are accomplished over a 3-wire serial port which allows reads and writes of the wiper position. Both potentiometers can be stacked for increased total resistance with the same resolution. For multiple-device, single-processor environments, the DS1867 can be cascaded for control over a single 3-wire bus.
The DS1867 is offered in three standard resistance values.
