NOTES:

1) All voltages are referenced to ground.

represents the current required when changing the wiper position.

6) Wiper load time is specified as the time required for the DS1804 to load the wiper position with the

than 2.7V.

7) The DS1804 is available in three resistor values. These include the DS1804-010, 10k

W; the DS1804-

050, 50k

W; and the DS1804-100, 100kW.

8) Valid at 25°C only.

9) Absolute linearity is used to compare measured wiper voltage versus expected wiper voltage as

determined by wiper position. The DS1804 is specified to provide an absolute linearity of ±0.60 LSB.

10) Relative linearity is used to determined the change in voltage between successive tap positions. The

DS1804 is specified to provide a relative linearity specification of ±0.25 LSB.

11) -3dB cutoff frequency characteristics for the DS1804 depend on potentiometer total resistance.

DS1804-010, 1MHz; DS1804-050, 200 kHz; and DS1804-100, 100 kHz.

12) Capacitance values apply at 25°C.

13) See Figure 2.

14) Power-up time is specified as the time required before the three-terminal control becomes active after

a stable power supply level has been reached.

allows the DS1804 three-terminal port to become inactive without writing the EEPROM memory of

the part.

of a new wiper position. The maximum time required to accomplish this task is specified at 10ms.
