Interface
The Intersil ISL95311 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 an I
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 wiper of the
potentiometer has an associated volatile Wiper Counter
Register (WR) and a non-volatile Initial Value Register (IVR)
that can be directly written to and read by the user. The
contents of the WR controls the position of the wiper on the
resistor array through the switches. At power-up, the device
recalls the contents of the IVR to the corresponding WR.
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications, including:
• LCD contrast control
• Parameter and bias adjustments
• Industrial and automotive control
• Mechanical pot replacement
