N57M5127

N57M5127 Product Preview 32‐tap Digital Potentiometer (POT) with Wiper Storage Description The N57M5127 is a single digital POTs designed as an electronic replacement for mechanical potentiometers and trim pots. Ideal for automated adjustments on high volume production lines, it is also well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment. The N57M5127 contains a 32-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. 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 N57M5127 is accomplished with three input control pins, CS, U/D, and INC. The I...
