PRELIMINARY
ISL90727
Single Volatile 128-Tap XDCP
Digitally Controlled Potentiometer
(XDCP)
The Intersil ISL90727 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. 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 SDA and SCL inputs.
The device can be used in a wide variety of applications
including:
Mechanical potentiometer replacement
Transducer adjustment of pressure, temperature, position,
chemical, and optical sensors
RF amplifier biasing
LCD brightness and contrast adjustment
Gain control and offset adjustment

NOTE: 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.
