NOTES:
1. All voltages are referenced with respect to ground.
2. Voltages across the potentiometer terminals (R
L
,R
W
,R
H
) cannot exceed V
CC
or go below ground by 0.5V.
3. Inputs UC and DC are internally pulled–up with resistance of 100K
.
4. UC and DC inputs are internally pulled–up to V
CC
via a 100K
resistor.
5. Active Current is specified when the inputs UC or DC are active.
6. Standby Current is the current consumed when the UC, DC , and STR inputs are inactive.
7. Input Pulse width is the minimum time required for an input to cause an increment or decrement.
8. Repetitive pulse inputs on UC or DC will be recognized as long as they are within 500 milliseconds of each other.
Pulses occuring faster than 1 ms apart may not be recognized as individual and separate pulses.
9. Input Pulse timing has tolerances to
±
10%
10.Capacitance values apply at 25
°
C.

=0.6V. Input logic levels are refer-
enced to ground.
12.If not used STR should be connected to ground.
13.The DS1809 is offered in three standard values a 10K
, 50K
, and 100K
.
14.The end–to–end resistance tolerance of the DS1809 can be expected to shift with temperature which is governed
by the temperature coefficient specification. The end–to–end resistance of the DS1809 will always remain within
a
±
20% tolerance regardless of temperature.
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 determined 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; 1 MHz, DS1809–050; 200 KHz, and the DS1809–100; 100 KHz.
18.Current leakage on the input control storage pin will require a typical 5 and maximum 8
μ
A to implement the auto–
storage feature.
19.A minimum time of 4 milliseconds between 2.2 volts and 1.7 volts is required on the input to the STR terminal when
using the part in the auto–storage configuration. The 2.2 volt to 1.7 volt range is a worst case condition for meeting
the power down storage requirements of the part.
