Serial Interface
The Intersil ISL23711 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 an I
2
C interface.
The potentiometer is implemented by a resistor array
composed of 127 resistive elements and a wiper switching
network. The wiper terminal can be connected to either end
of the resistor array or at any one of the Tap Positions in
between, providing 128 steps of resolution between R
L
and
R
H
. The 鈥減osition鈥?of the wiper is determined by the value
assigned to the volatile Wiper Register (WR). The WR can
be directly written to and read from using standard I
2
C
interface protocol. The device is available in either a 10k鈩?or
50k鈩?version.
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including:
鈥?Industrial and Automotive Control
鈥?Parameter and Bias Adjustments
鈥?Amplifier Bias and Control

NOTES:
1. Add 鈥?T鈥?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.
