PROGRAMMING THE POTENTIOMETER DIVIDER  
Voltage Output Operation  
APPLICATIONS INFORMATION  
The negative-edge sensitive CLK pin does not contain any  
internal debounce circuitry. This standard CMOS logic input  
responds to fast negative edges and needs to be debounced  
externally with an appropriate circuit designed for the type of  
switch closure device being used. Good performance results at  
the CLK input pin when the negative logic transition has a  
minimum slew rate of 1 V/µs. A wide variety of standard circuits  
can be used such as a one-shot multivibrator, Schmitt Triggered  
gates, cross coupled flip-flops, or RC filters to drive the CLK  
pin with uniform negative edges. This will prevent the digital  
potentiometer from skipping output codes while counting due to  
switch contact bounce.  
The digital potentiometer easily generates an output voltage  
proportional to the input voltage applied to a given terminal.  
For example connecting A Terminal to +5 V and B Terminal to  
ground produces an output voltage at the wiper which can be  
any value starting at zero volts up to 1 LSB less than +5 V. Each  
LSB of voltage is equal to the voltage applied across terminals  
AB divided by the 128-position resolution of the potentiometer  
divider. The general equation defining the output voltage with  
respect to ground for any given input voltage applied to termi-  
nals AB is:  
VW(D) = D/128 × VAB + VB  
(1)  
D represents the current contents of the internal UP/DOWN  
counter.  
Operation of the digital potentiometer in the divider mode re-  
sults in more accurate operation over temperature. Here the  
output voltage is dependent on the ratio of the internal resistors,  
not the absolute value, therefore, the drift improves to 20 ppm/°C.
