OPERATION The AD5203 provides a quad channel, 64-position digitally- controlled variable resistor (VR) device. Changing the pro- grammed VR settings is accomplished by clocking in an 8-bit serial data word into the SDI (Serial Data Input) pin. The for- mat ...

AD5203 PROGRAMMING THE POTENTIOMETER DIVIDER Voltage Output Operation The digital potentiometer easily generates an output voltage proportional to the input voltage applied to a given terminal. For example connecting A–terminal and B–terminal to ground produces an output ...

The data setup and data hold times in the specification table determine the data valid time requirements. The last eight bits of the data word entered into the serial register are held when CS returns high. At the same time ...
