Product Summary

The DS1669-10 is a digital rheostat or potentiometer. The DS1669-10 supports 64 possible uniformtap points over the entire resistive range. The standard resistive ranges are 10 kΩ, 50 kΩ, and 100 kΩ.The Dallastat can be controlled by either a switch contact closure input or a digital source input such as a CPU. Wiper position is maintained in the absence of power through the use of a EEPROM memory cellarray. The EEPROM cell array will withstand more than 50,000 writes.
