CAT5116
Log‐taper, 100‐tap
Digital Potentiometer (POT)
Description The CAT5116 is a log-taper single digital POT designed as an
electronic replacement for mechanical potentiometers. Ideal for automated adjustments on high volume production lines,
ICs are well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment.
The CAT5116 contains a 100-tap series resistor array connected between two terminals RH and RL. An up/down counter and decoder that are controlled by three input pins, determines which tap is connected to the wiper, RW.
The wiper setting, stored in nonvolatile memory, is not lost when the device is powered down and is automatically reinstated when power is returned.
