Low Noise/Low Power/I

The X95820 integrates two digitally controlled

potentiometers (XDCP) 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

volatile Wiper Register (WR) and a non-volatile Initial Value

user. The contents of the WR controls the position of the

wiper. At power up the device recalls the contents of the two

DCP’s IVR to the corresponding WRs.

The DCPs 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.

Ordering Information

*Add "T1" suffix for tape and reel.

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.
