Serial Interface
The Intersil ISL95711 is a digitally controlled potentiometer
(XDCP). The device consists of a resistor array, wiper
switches, a control section, and nonvolatile memory. The
wiper position is controlled by a 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). This register
has an associated non-volatile Initial Value Register (IVR).
The value stored in the IVR will be written into the WR at
power-up, allowing wiper position recall after power
interruption. The WR and the IVR 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.
