Intersil ISL90460UIE527

Description
The Intersil ISL90460 is a digitally controlled potentiometer (XDCP) configured as a variable resistor. It consists of a resistor array, wiper switches, a control section, and volatile memory. The wiper position is controlled by a 2-pin 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.
