Working Principles
The CAT5112VI50 is a digital potentiometer that uses a series of resistive elements and switches controlled by digital signals. The resistance between the wiper terminal (W) and either the high terminal (H) or low terminal (L) can be adjusted digitally using the serial data input (SDA) and serial clock input (SCL). The non-volatile memory ensures that the resistance setting is retained even when power is disconnected.
