Data Sheet
October 14, 2005
FN8229.3
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:
鈥?LCD contrast control
鈥?Parameter and bias adjustments
鈥?Industrial and Automotive Control
鈥?Transducer adjustment of pressure, temperature, position,
chemical, and optical sensors
鈥?Laser Diode driver biasing
鈥?Gain control and offset adjustment
