DESCRIPTION
The DS1869 Dallastat
TM 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
, 50 k, and 100 k.
The Dallastat can be controlled by either a switch contact closure input or a digital source input such as a
CPU. The DS1869 operates from 3V or 5V supplies. 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 DS1869 is offered in two standard IC packages which include an 8-pin 300-mil DIP and an 8-pin
208-mil SOIC. The DS1869 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 DS1869
pinouts allow access to both ends of the potentiometer RL, RH, and the wiper, RW. Control inputs include
the digital source input, D, the up contact input, UC, and the down contact input, DC. Other pins include
the positive, +V, and negative, -V, supply inputs. The DS1869 is specified to operate from -40°C to
+85°C.
