DS1804
6 of 10
NOTES:
1) All voltages are referenced to ground.
2) Valid for VCC = 5V only.
3) Resistor input voltages cannot go below ground or exceed VCC by the amounts as shown in the table.
4) Maximum current specifications are based on the clock rate of INC input. This specification
represents the current required when changing the wiper position.
5) Standby current levels apply when all inputs are driven to appropriate supply levels. CS , INC , U/ D =
VCC.
6) Wiper load time is specified as the time required for the DS1804 to load the wiper position with the
contents of nonvolatile memory once VCC has reached a stable operating voltage equal to or greater
than 2.7V.
7) The DS1804 is available in three resistor values. These include the DS1804-010, 10k
; the DS1804-
050, 50k
; and the DS1804-100, 100k.
8) Valid at TA = +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, 200kHz; and DS1804-100, 100kHz.
12) Capacitance values apply at TA = +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.
15) At VCC = 2.7V, VIL = 0.8V.
16) The INC low to CS inactive is specified to be 50ns minimum. This is the transition condition which
allows the DS1804 three-terminal port to become inactive without writing the EEPROM memory of
the part.
17) Wiper Storage Time, tWST, is the time require for the DS1804 to write EEPROM memory for storage
of a new wiper position. The maximum time required to accomplish this task is specified at 10ms.
