ISL22343
Quad Digitally Controlled Potentiometer (XDCP™)
Data Sheet
August 17, 2015
FN6423.2
Low Noise, Low Power, I2C Bus, 256 Taps
The ISL22343 integrates four digitally controlled
potentiometers (DCP), control logic and non-volatile memory
on a monolithic CMOS integrated circuit.
The digitally controlled potentiometer is implemented with a
combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
I2C bus interface. The potentiometer has an associated
volatile Wiper Register (WRi) and a non-volatile Initial Value
Register (IVRi) that can be directly written to and read by the
user. The contents of the WRi control the position of the
corresponding wiper. At power up the device recalls the
contents of the DCP’s IVRi to the correspondent WRi.
The ISL22343 also has 11 general purpose non-volatile
registers that can be used as storage of lookup table for
multiple wiper position or any other valuable information.
The ISL22343 features a dual supply, that is beneficial for
applications requiring a bipolar range for DCP terminals
between V- and VCC.
Each DCP can be used as three-terminal potentiometers or
as two-terminal variable resistors in a wide variety of
applications including control, parameter adjustments, and
signal processing.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte
tin plate PLUS ANNEAL - e3 termination finish, which is 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 tape and reel. Please refer to TB347 for details on reel specifications
