DESCRIPTION

The DS1809 Dallastat is a nonvolatile digitally controlled potentiometer that provides 64 uniform wiper

positions over the entire resistor range; including the high-end and low-end terminals of the device. The

DS1809 is a low-power device capable of operating from power supplies of +4.5V to +5.5V. The device

is ideal for low-power, portable, or battery powered applications.

Wiper position is maintained in the absence of power. This is accomplished via the use of an EEPROM

cell array. The device provides for two storage methods, which include an autostore capability and a

command-initiated storage function. The EEPROM cell array is specified to accept greater than 50k

writes. Storage of the wiper position is discussed in the Wiper Storage section of this data sheet.

Wiper positioning is controlled via a dual pushbutton (or contact closure) interface. For simple

pushbutton-controlled applications or CPU-generated control signals, external debounce circuitry is not

needed. The control interface will support both repetitive pulse inputs and continuous pulse (“push-and-

hold”) inputs. Repetitive pulse and continuous pulse control as well as timing diagrams are discussed in

the Operation.

The DS1809 is available in standard 10 kΩ, 50 kΩ, and 100 kΩ resistor versions. The DS1809 is

provided as an industrial temperature grade part only. Available packaging for the DS1809 include an 8-

lead (300-mil) PDIP, an 8-lead (150-mil) SO, and an 8-lead (118-mil) µSOP.
