Working Principles

The CAT5115VI00 is a digital potentiometer that utilizes an internal array of resistive elements and switches controlled by an I2C interface. The resistance value can be adjusted digitally by sending commands through the I2C bus. The device stores the resistance setting in non-volatile memory, ensuring it remains unchanged even after power loss.

Detailed Application Field Plans

1. Audio Equipment: Volume control, tone adjustment
2. Industrial Control Systems: Calibration, fine-tuning
