Volatile Digitally Controlled Potentiometer (XDCP™)
Data Sheet
August 22, 2005
FN6126.0
Terminal Voltage ±3V or ±5V, 128 Taps
Up/Down Interface
The Intersil ISL23710 is a digitally controlled potentiometer
(XDCP). The device consists of a resistor array, wiper
switches, and a control section. The wiper position is
controlled by a Up/Down interface.
The potentiometer is implemented by a resistor array
composed of 127 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, U/D, and INC inputs.
The wiper register is volatile and is reset to midscale on
power up. The wiper position can be locked while powered
up to prevent inadvertent changes.
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including:
• Industrial and Automotive Control
• Parameter and Bias Adjustments
• Amplifier Bias and Control

NOTES:
1. Add “-T” suffix for tape and reel.
2. Intersil Pb-free plus anneal products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
