DATASHEET ISL90462 Single Volatile 32-tap XDCP Digitally Controlled Potentiometer (XDCP™) FN8230 Rev 4.00 October 20, 2015 The Intersil ISL90462 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
