determined by the logic state of the U/
D
input. The
CS
input is used to select the device.
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.
For a pin-compatible device that recalls a stored tap
position on power-up refer to the CAT5114 data sheet.
FUNCTIONAL DIAGRAM
DESCRIPTION
The CAT5115 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 CAT5115 contains a 32-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 is always set to the mid point, tap
15 at power up. The tap position is not stored in memory.
Wiper-control of the CAT5115 is accomplished with
three input control pins,
CS
, U/
D
, and
INC
. The
INC
input increments the wiper in the direction which is
