Functional Features

• Dual-channel design allows independent adjustment of two resistive elements.
• High resolution of 8 bits provides precise resistance settings.
• I2C-compatible interface enables easy integration with microcontrollers and other digital devices.
• Non-volatile memory ensures that the wiper position is retained even when power is removed.
• Low power consumption makes it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages: - Precise resistance adjustment with high resolution - Dual-channel capability for independent control - Non-volatile memory for storing wiper position - Low power consumption

Disadvantages: - Limited resistance range (up to 200Ω) - Requires I2C communication interface

Working Principles

The AD5262BRUZ200 operates by digitally controlling the resistance between its wiper terminals and corresponding fixed terminals. The desired resistance value is set using the I2C-compatible interface, which sends commands to adjust the wiper position. The non-volatile memory ensures that the wiper position is retained even when power is removed.
