Additional Details:

The X9313WST6 XDCP features a resistor array consisting of 100 discrete resistance steps. The wiper position is controlled by a digital code transmitted via the SPI serial interface. The device includes non-volatile memory (EEPROM) to store the wiper position, ensuring that the desired resistance setting is retained even after power is removed. The SPI interface allows for easy communication with microcontrollers and other digital devices. The device operates from a single power supply and consumes very little power. The wide operating voltage range provides flexibility in various applications. This device is available in a small surface-mount package, making it suitable for compact designs. The digital control of the potentiometer allows for automated adjustments and remote control capabilities. The absence of mechanical components eliminates the wear and tear associated with traditional potentiometers, resulting in improved reliability and longer lifespan. The X9313WST6 is a versatile and reliable solution for applications requiring precise and programmable resistance control. The device offers accurate adjustments, and because of its non-volatile memory, it will maintain the wiper position even after power to the device is removed.
