FEATURES
§ Nonvolatile version of the popular DS1267
§ Low power consumption, quiet, pumpless
design
§ Operates from single 5V or
±5V supplies
§ Two digitally controlled, 256-position
potentiometers
§ Wiper position is maintained in the absence of
power
§ Serial port provides means for setting and
reading both potentiometers
§ Resistors can be connected in series to
provide increased total resistance
§ 16-pin SOIC and 20-pin TSSOP for surface
mount applications
§ Standard resistance values:
-
DS1867-10 ~ 10 k
-
DS1867-50 ~ 50 k
-
DS1867-100 ~ 100 k
§ Operating Temperature Range:
-
Industrial: -40
°C to +85°C
