Available in PDIP, SOIC, TSSOP and MSOP packages

new system values without effecting the stored
setting. Wiper-control of the CAT5113 is
accomplished with three input control pins,
CS
, U/
D
,
and
INC
. The
INC
input increments the wiper in the
direction which is determined by the logic state of
the U/
D
input. The
CS
input is used to select the
device and also store the wiper position prior to
power down.
The digitally programmable potentiometer can be
used as a three-terminal resistive divider or as a
two-terminal variable resistor. DPPs bring variability and
programmability to a wide variety of applications
including control, parameter adjustments, and
signal processing.
FUNCTIONAL DIAGRAM
DESCRIPTION
The CAT5113 is a single digitally programmable
potentiometer (DPP) designed as a electronic
replacement for mechanical potentiometers and trim
pots. Ideal for automated adjustments on high volume
production lines, they are also well suited for
applications where equipment requiring periodic
adjustment is either difficult to access or located in a
hazardous or remote environment.
The CAT5113 contains a 100-tap series resistor array
connected between two terminals R
H
and R
L
. An up/
down counter and decoder that are controlled by three
input pins, determines which tap is connected to the
wiper, R
W
. The wiper setting, stored in nonvolatile
memory, is not lost when the device is powered
down and is automatically reinstated when power
is returned. The wiper can be adjusted to test
