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

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 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 device is used as a two-terminal variable resistors. Digital POTs

bring variability and programmability to a wide variety of applications

including control, parameter adjustments, and signal processing.
