Additional Details

The X9312ZP has a total resistance of 10 kΩ. The wiper position is controlled via a three-wire serial interface, allowing easy adjustment and storage of the desired resistance value. The device features non-volatile memory, ensuring that the wiper position is retained even after the power supply is removed. It operates from a single +5V supply and consumes very little power. The X9312ZP is available in a PDIP package.

This digital potentiometer eliminates the need for manual trimmers, making automated calibration and adjustment possible. Its precise control and non-volatile storage capabilities ensure consistent performance over time. The simple serial interface allows for easy integration into microcontroller-based systems, reducing development time and complexity. Its low power consumption is also a significant advantage in battery-powered applications. The X9312ZP is a versatile and reliable solution for applications requiring digitally adjustable resistance.
