13. The DS1809 is offered in three values: 10kΩ , 50kΩ , and 100kΩ .
DS1809
14. Valid at 25°C 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.
17. -3 dB cutoff frequency characteristics for the DS1809 depend on the potentiometer’s total resistance.
DS1809-010: 1 MHz; DS1809-050: 200 kHz; and the DS1809-100: 100 kHz.
18. Current leakage on the input control storage pin will require a typical 5 µA and maximum 8 µA to
implement the auto-storage feature.
19. A minimum time of 4 milliseconds between 2.2 volts and 1.7 volts is required on the input to the STR
terminal when using the part in the auto-storage configuration. The 2.2-volt to 1.7-volt range is a
worst case condition for meeting the power-down storage requirements of the part.
