NOTES:
1. All voltages are referenced to ground.
2. Valid for V
CC
= 5V only.
3. Resistor input voltages cannot go below ground or exceed V
CC
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 cur-
rent required when changing the wiper position.
5. Standby current levels apply when all inputs are driven to appropriate supply levels. CS, INC, U/D = V
CC
.
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 V
CC
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. The end–to–end resistance tolerance of the DS1804 can be expected to shift with temperature. However, this
change will not exceed
±
20% of the nominal resistor value of the part.
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. –3 dB cutoff frequency characteristics for the DS1804 depend on potentiometer total resistance. DS1804–010,
1 MHz, DS1804–050; 200 KHz, and DS1804–100; 100 KHz.
