Description

The Intersil ISL90461 is a digitally controlled potentiometer (XDCP). Configured as a variable resistor, the ISL90461 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 ISL90461 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 ISL90461 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
