Specifications of DS1804Y-010

• Part # Aliases: 90-1804Y-010

NOTES:
1) All voltages are referenced to ground.
2) Valid for V
3) Resistor input voltages cannot go below ground or exceed V
4) Maximum current specifications are based on the clock rate of
5) Standby current levels apply when all inputs are driven to appropriate supply levels.
6) Wiper load time is specified as the time required for the DS1804 to load the wiper position with the
7) The DS1804 is available in three resistor values. These include the DS1804-010, 10kΩ; the DS1804-
8) Valid at T
9) Absolute linearity is used to compare measured wiper voltage versus expected wiper voltage as
10) Relative linearity is used to determined the change in voltage between successive tap positions. The
11) -3dB cutoff frequency characteristics for the DS1804 depend on potentiometer total resistance.
12) Capacitance values apply at T
13) See Figure 2.
14) Power-up time is specified as the time required before the three-terminal control becomes active after
