14. Valid at 25C only.
15. Absolute linearity is used to compare measured wiper voltage versus expected wiper voltage as
16. Relative linearity is used to determine the change in voltage between successive tap positions. The
17. -3 dB cutoff frequency characteristics for the DS1809 depend on the potentiometer’s total resistance.
18. Current leakage on the input control storage pin will require a typical 5 A and maximum 8 A to
19. A minimum time of 4 milliseconds between 2.2 volts and 1.7 volts is required on the input to the STR
determined by wiper position. The DS1809 is specified to provide a absolute linearity of ±0.60 LSB.
DS1809 is specified to provide a relative linearity specification of ±0.25 LSB.
DS1809-010: 1 MHz; DS1809-050: 200 kHz; and the DS1809-100: 100 kHz.

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.
