Low Noise/Low Power/I

The X95840 integrates four 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 four

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.
