Working Principles

The AD5246BKSZ100-R2 is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistor network and a digital control circuit. The resistance value can be adjusted digitally through the I2C interface, eliminating the need for manual adjustment.

When a digital value is sent via the I2C bus, the internal control circuit converts it into an analog voltage across the resistor network. This voltage determines the effective resistance between the wiper terminal and one of the end terminals. By changing the digital value, the resistance can be varied in small increments, allowing precise control over the output voltage or current in a circuit.
