... 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. ...

... The DS1809 is available in standard 10 k, 50 k, and 100 kresistor versions. The DS1809 is provided as an industrial temperature grade part only. Available packaging for the DS1809 include an 8- lead (300-mil) DIP an 8-lead (150-mil) SOIC, and an 8-lead (118-mil) SOP.

... The total time to transcend the entire potentiometer given a continuous pulse input is provided by the equation: ½(second 100 ms = 6.7 (seconds) If the wiper position of the DS1809 is incremented to an end-position, it will stay at that position until the device receives an opposite direction input pulse command over the inputs. For example, if the wiper position is incremented to the R until UC is first deactivated, and then the DC input is activated to move the wiper position towards the R terminal ...

... Command initiated storage operations will require a minimum complete the storage operation. This measured from the rise of STR input (see Figure 5). For applications not requiring or using the nonvolatile memory feature of the DS1809 recommended that the STR input be connected to GND. ...

... Pulses occurring faster than 1 ms apart may not be recognized as individual and separate pulses. 9. Input pulse timing has tolerances to ±10%. 10. Capacitance values apply at 25°C. 11. For V = 5V±10%, maximum V CC 12. If not used STR should be connected to ground. 13. The DS1809 is offered in three values: 10 k, 50 k, and 100 k. SYMBOL MIN TYP ...

... Valid at 25C only. 15. Absolute linearity is used to compare measured wiper voltage versus expected wiper voltage as determined by wiper position. The DS1809 is specified to provide a absolute linearity of ±0.60 LSB. 16. Relative linearity is used to determine the change in voltage between successive tap positions. The DS1809 is specified to provide a relative linearity specification of ±0.25 LSB. ...
