Digital Potentiometer Breakout: X9C103S

Features:

• Operating Voltage: 3V - 5V
• Chipset: X9C103S
• Board Dimensions: 27mm x 13mm
• Center Tap Resistance Range: 0 to 10K Ohm
• Digitally controlled potentiometer
• Consists of a resistor array, wiper switches, a control section, and non-volatile memory
• Wiper position is controlled by a three-wire interface
• Contains resistor array composed of 99 resistive elements and a wiper switching network to achieve variable resistance
• Between each element and at either end are tap points accessible to the wiper terminal
• Position of the wiper element is controlled by the CS, U/D, and INC inputs
• Position of the wiper can be stored in non-volatile memory and then be recalled upon a subsequent power-up operation
• Can be used as a three-terminal potentiometer or as a two-terminal variable resistor
