ISL90461

Digitally Controlled Potentiometer (XDCP™)

Single Volatile 32-Tap 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 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.

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
