- The X9C104 are Intersils digitally controlled (XDCP) potentiometers.
- The device consists of a resistor array, wiper switches, a control section, and non-volatile memory.
- The wiper position is controlled by a three-wire interface.
The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network.
- Between each element and at either end are tap points accessible to the wiper terminal.
- The position of the wiper element is controlled by the CS, U/D, and INC inputs.
- The position of the wiper can be stored in non-volatile memory and then be recalled upon a subsequent power-up operation.
The device can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications ranging from control to signal processing to parameter adjustment.
