X9C103S 10K Digital Potentiometer Module

The X9C103S Digital Potentiometer Module is a 10kΩ digitally controlled potentiometer with 100 selectable wiper taps and non-volatile storage of the current tap point.

Quick Spec

• 0-10kΩ with 100 steps
• Use as 3-terminal potentiometer or 2-terminal variable resistor
• 3-wire control interface
• Up to ±5V across the potentiometer end-points
• 4.4mA current sink or source capability
• Red power LED is lit when power is applied
• 5V logic compatible
• Dimensions: 27 x 14mm

Pinout

• VCC: Vcc power (4.5 to 5.5V)
• CS: Chip Select. Active LOW
• INC: Increment. Pulsing this pin low causes the wiper to move on the negative (falling) edge of the pulse
• U/D: Up / Down. Determines the direction of travel of the wiper when the module is incremented. Logic HIGH moves the wiper UP and logic LOW moves the wiper down.
• GND: Ground
• VL: Voltage Low is the voltage for the lower end of the potentiometer. This is normally ground or the lower of two voltages
• VW: Voltage Wiper is the voltage output of the adjustable wiper contact
• VH: Voltage High is the voltage at the upper end of the potentiometer. This is normally the higher voltage.

Note that just like a regular potentiometer, you can switch the voltages between VL and VH as to which one is more positive, but doing so will reverse the direction of the U/D movement.
