Working Principles

The AD5262BRU200-REEL7 is a digital potentiometer that replaces traditional mechanical potentiometers in electronic circuits. It consists of two independent channels, each capable of providing a resistance value between 0 and 200 Ohms. The resistance is controlled digitally through an I2C interface, allowing for precise adjustments.

When a resistance value is set, the AD5262BRU200-REEL7 adjusts its internal resistive network to match the desired value. The non-volatile memory ensures that the resistance settings are retained even when power is disconnected.
