ISL95810

Single Digitally Controlled Potentiometer (XDCP™)

The ISL95810 integrates a digitally controlled potentiometer

(XDCP) on a monolithic CMOS integrated circuit.

The digitally controlled potentiometer is implemented with a

combination of resistor elements and CMOS switches. The

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.

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.

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.
