Single Digitally Controlled Potentiometer (XDCP™)
Data Sheet
October 7, 2005
FN8090.1
2
Low Noise, Low Power I C Bus, 256 Taps
Features
• 256 resistor taps - 0.4% resolution
The ISL95810 integrates a digitally controlled potentiometer
(XDCP) on a monolithic CMOS integrated circuit.

• I C serial interface
The digitally controlled potentiometer is implemented with a
combination of resistor elements and CMOS switches. The
• Wiper resistance: 70Ω typical @ 3.3V
• Non-volatile storage of wiper position
• Standby current 5µA max
2
position of the wiper is controlled by the user through the I C
bus interface. The 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 content of the WR controls the position of the wiper. At
power-up the device recalls the contents of the DCP’s IVR to
the WR.
• Power supply: 2.7V to 5.5V
• 50kΩ, 10kΩ total resistance
• High reliability
- Endurance: 200,000 data changes per bit per register
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.
- Register data retention: 50 years @ T ≤ 75°C
• 8 Ld MSOP and 8 Ld TDFN packaging
• 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.
