DESCRIPTION
The
X9269
integrates
2
digitally
controlled
potentiometer
(XDCP)
on
a
monolithic
CMOS
integrated circuit.
The digital controlled potentiometer is implemented
using 255 resistive elements in a series array.
Between each element are tap points connected to the
wiper terminal through switches. The position of the
wiper on the array is controlled by the user through the
2-Wire
bus
interface.
Each
potentiometer
has
associated with it a volatile Wiper Counter Register
(WCR) and a four nonvolatile Data Registers that can
be directly written to and read by the user. The
contents of the WCR controls the position of the wiper
on the resistor array though the switches. Powerup
recalls the contents of the default Data Register (DR0)
to the WCR.
The
XDCP
can
be
used
as
a
three-terminal
potentiometer or as a two terminal variable resistor in
a wide variety of applications including control,
parameter adjustments, and signal processing.
