Single Digitally Controlled Potentiometer (XDCP™) Low Noise/Low Power/I C
Bus/256 Taps
The ISL90810 integrates a digitally controlled potentiometer
(XDCP) on a monolithic CMOS integrated circuit.
Features
• 256 resistor taps - 0.4% resolution
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
2
• I C serial interface with write/read capability
• Power-on preset to mid-scale (128 tap position)
• Wiper resistance: 70 typical @ 3.3V
• Standby current 5µA max
2
I C bus interface. Each potentiometer has an associated
Wiper Register (WR) that can be directly written to and read
by the user. The contents of the WR controls the position of
the wiper. When powered on the ISL90810’s wiper will
always commence at mid-scale (128 tap position).
• Power supply: 2.7V to 5.5V
• 50k, 10k total resistance
The DCP can be used as three-terminal potentiometer or as
two-terminal variable resistor in a wide variety of applications
including control, parameter adjustments, and signal
processing.
• 8 Ld MSOP
• Pb-free plus anneal available (RoHS compliant)

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.
