DESCRIPTION
The
potentiometers (XDCP) on a monolithic CMOS inte-
grated circuit.
X95840
integrates
four
digitally
controlled
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-wire bus interface. Each potentio-
meter 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 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.
