Description

The Intersil ISL90462 is a digitally controlled potentiometer (XDCP). Configured as a variable resistor, the ISL90462 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 ISL90462 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. The device can be used in a wide variety of applications including: LCD contrast control Parameter and bias adjustments Industrial and Automotive Control Transducer adjustment of pressure, temperature, position, chemical, and optical sensors Laser Diode driver biasing Gain control and offset adjustment
