ISL90460
Single Volatile 32-Tap XDCP™
Digitally Controlled Potentiometer (XDCP)
The Intersil ISL90460 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
