Product Summary

The DS1867S-50 is a Dual Digital Potentiometer with EEPROM. It is the nonvolatile version of the popular DS1267 Dual Digital Potentiometer. The DS1867S-50 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 DS1867S-50 can be cascaded for control over a single 3-wire bus. The DS1867S-50 is offered in three standard resistance values.
