Dallastat 64-Position Linear Taper

Maxim Integrated 

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: 1MHz; DS1809-050: 200kHz; and the DS1809-100: 100kHz.

18. Current leakage on the input control storage pin will require a typical 5µA and maximum 8µA to

implement the auto-storage feature.

19. A minimum time of 4ms between 2.2V and 1.7V is required on the input to the STR terminal when

using the part in the auto-storage configuration. The 2.2V to 1.7V range is a worst case condition for

meeting the power-down storage requirements of the part.
