NV, I C, Stepper Potentiometer  
DS503  
General Description  
Features  
The DS3503 features two synchronized stepping digital  
potentiometers: one 7-bit potentiometer with RW as its  
output, and another potentiometer with Y as its output.  
Both potentiometers reference the RH and RL terminals  
and feature an output voltage range of up to 15.5V. In  
addition, both potentiometer outputs can be stepped  
up and down by configuring the control registers.  
128 Wiper Tap Points  
Full-Scale Resistance: 5kΩ  
Programmable Logic Lets WR Step Up and Down  
with Timing Controlled by SYNC Input  
Second Potentiometer Output Pin (Y) Centered at  
Position 40h
