X9C503 Digitally Controlled Potentiometer

PIN NUMBER 1 2 3 4 5 6 7 8 PIN NAME INC U/D VH/RH VSS VW/RW RL/VL CS VCC DESCRIPTION INCREMENT The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the U/D input. UP/DOWN The U/D .

DATASHEET X9C102, X9C103, X9C104, X9C503 Digitally Controlled Potentiometer (XDCP™) The X9C102, X9C103, X9C104, X9C503 are digitally controlled (XDCP) potentiometers. The device consists of a resistor array, wiper switches, a control section, and nonvolatile 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 point.
