ISL90461 Single Volatile 32-Tap XDCP Digitally Controlled Potentiometer (XDCP™) The Intersil ISL90461 is a digitally controlled potentiometer (XDCP). Configured as a variable resistor, the device consists of a resistor array, wiper switches, a control section, and volatile memory. The wiper position is controlled by a 2pin Up /Down interface. The potentiometer is implemented by a resistor array composed of 31 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 and U/D inputs.
