The X9C103S is a digitally controlled (XDCP) potentiometer designed for Arduino projects. It features a resistor array, wiper switches, and non-volatile memory. The wiper position is controlled via a three-wire interface, allowing precise adjustments. The potentiometer consists of 99 resistive elements and a wiper switching network, providing flexibility in voltage control.
The device's input control section functions as an up/down counter, with the output decoded to activate electronic switches connecting the resistor array to the wiper output. The non-volatile memory stores the wiper position for future use, ensuring consistent performance across power cycles. The resistor array comprises 99 individual resistors connected in series, enabling fine-grained adjustments.
With a wide input voltage range of -5V to +5V, the X9C103S is versatile for various applications. The internal charge pump supports different voltage levels, offering convenience with a single power supply. Consider the charge pump noise of 20mV at 850kHz when designing your circuit for optimal performance.
