CAT5113/D
CAT5113
100‐tap Digital
Potentiometer (POT)
Description
The CAT5113 is a single digital POT designed as an electronic
replacement for mechanical potentiometers. 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 new system values without affecting 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 digital POT can be used as a three-terminal resistive divider or
as a two-terminal variable resistor.
