In a system where there may be multiple Digitally Controlled Potentiometers (DCPs) it is often difficult to control each potentiometer individually. Normally this requires the use of a microcontroller. However, microcontrollers are difficult to program and requires production control of the software. This application shows a simple hardware approach that works with multiple potentiometers having the 3-wire interface (INC, U/D, and CS.) It provides a familiar rotary action to move the potentiometers up and down and provides a store option for non-volatile DCPs.The circuit is demonstrated using two dual X93254 potentiometers.
