DESCRIPTION
The DS1809 Dallastat is a nonvolatile digitally con-
trolled 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, low voltage device capable of
operating from power supplies of +2.7V to +5.5V. The
device is ideal for low–power, portable, or battery pow-
ered 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 auto–store capability and a com-
mand–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 datasheet.
Wiper positioning is controlled via a patented dual
push–button (or contact closure) interface. For simple
push–button controlled applications or CPU generated
control signals, external debounce circuitry is not
needed. The control interface will support both repeti-
tive pulse inputs and continuous pulse (“push–and–
hold”) inputs. Repetitive pulse and continuous pulse
control, as well as, timing diagrams are discussed in the
section entitled “OPERATION”.
The DS1809 is available in standard 10K
, 50K
, and
100K
resistor versions. The DS1809 is provided as an
industrial temperature grade part only. Available pack-
aging for the DS1809 include an 8–lead (300 mil) DIP
an 8–lead (150 mil) SOIC, and an 8–lead (118 mil)
μ
SOP.
