DESCRIPTION
The CAT5127/CAT5129 are single digitally programmable
potentiometers (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 CAT5127 contains a 32-tap series resistor array
connected between two terminals R
CAT5129 contains a 32-tap series resistor array
connected between two terminals R
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
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 effecting the stored setting.
Wiper-control
accomplished with three input control pins, CS
and INC
direction which is determined by the logic state of the
U/D ¯ input. The CS
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.
