DESCRIPTION
The DS1669 Dallastat is a digital rheostat or potentiometer. This device provides 64 possible uniform tap
points over the entire resistive range. The standard resistive ranges are 10 k
W, 50 kW, and 100 kW. 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 cell
array. The EEPROM cell array will withstand more than 50,000 writes.
The DS1669 is offered in two standard IC packages which include an 8-pin 300-mil DIP and an 8-pin
208-mil SOIC. The DS1669 can be configured to operate using a single pushbutton, dual pushbutton or
digital source input by varying power-on conditions. This is illustrated in Figures 1 and 2. The DS1669
pinouts allow access to both ends of the potentiometer RL, RH, and the wiper, RW. Control inputs include
