DESCRIPTION

The DS1669 Dallastat^TMis a digital rheostat or potentiometer. This device provides 64 possible uniform

tap 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 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 R_L, R_H, and the wiper, R_W. Control inputs include
