ISL22449
Quad Digitally Controlled Potentiometer (XDCP)
Low Noise, Low Power, SPI
Bus, 128 Taps,
Wiper Only
The ISL22449 integrates four digitally controlled
potentiometers (DCP) and non-volatile memory on a
monolithic CMOS integrated circuit.
The digitally controlled potentiometers are implemented with
a combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
SPI serial interface. Each potentiometer has an associated
volatile Wiper 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. At power-up the device recalls the contents of the
DCP’s IVR to the corresponding WR.
The DCP can be used as a voltage divider in a wide variety
of applications including control, parameter adjustments, AC
measurement and signal processing.

NOTES:
1. 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.
2. Add “-TK” suffix for 1,000 Tape and Reel option
