Overview
CAT5127, CAT5129 32‐tap Digital Potentiometers (POTs) Description The CAT5127/CAT5129 are single digital POTs designed as an 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 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 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 of the ...
