DESCRIPTION
The CAT5127/CAT5129 are single digitally program–
mable potentiometers (DPP™) designed as a electro–
nic 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 CAT5127 contains a 32-tap series resistor array
connected between two terminals RH and RL. The
CAT5129 contains a 32-tap series resistor array
connected between two terminals RH and GND. An
up/down counter and decoder that are controlled by
three input pins, determines which tap is connected to
the wiper. The wiper setting, stored in nonvolatile me–
mory, 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 effecting the stored setting.
Wiper-control of the CAT5127/CAT5129 is
accomplished with three input control pins, C¯¯S, U/D¯,
and I¯N¯C¯. The I¯N¯C¯ input increments the wiper in the
direction which is determined by the logic state of the
U/D¯ input. The C¯¯S input is used to select the device
and also store the wiper position prior to power down.
The devices are used as two-terminal variable
resistors. DPPs bring variability and programmability
to a wide variety of applications including control,
parameter adjustments, and signal processing.
