The CAT5112 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 CAT5112 contains a 32-tap series resistor array

connected between two terminals R

down counter and decoder that are controlled by three

input pins, determines which tap is connected to the

wiper, R

amp that operates rail to rail. The wiper setting, stored in

non-volatile NVRAM memory, is not lost when the de-

vice is powered down and is automatically recalled when

power is returned. The wiper can be adjusted to test new

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 digitally programmable potentiometer can be

used as a buffered voltage divider. For applications

where the potentiometer is used as a 2-terminal variable

resistor, please refer to the CAT5114. The buffered

wiper of the CAT5112 is not compatible with that appli-

cation. DPPs bring variability and programmability to a

broad range of applications and are used primarily to

control, regulate or adjust a characteristic or parameter

of an analog circuit.
