... DS1668, DS1669, DS1669S DESCRIPTION The DS1668 and DS1669 Dallastats are digital rheo- stats or potentiometers. These units provide 64 pos- sible uniform tap points over the resistive range and are available in standard versions of 10K, 50K, and 100K ohms. The Dallastats can be controlled by either a mechanical– ...
