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.
