N57M5114 32tap Digital Potentiometer (POT) Description The N57M5114 is a single digital POT designed as an electronic replacement for mechanical potentiometers and trim pots. Ideal for www.onsemi.com 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 N57M5114 contains a 32-tap series resistor array connected between two terminals R and R . An up/down counter and decoder SOIC8 MSOP8 H L V SUFFIX Z SUFFIX that are controlled by three input pins, determines which tap is CASE 751BD CASE 846AD connected to the wiper, R . The wiper setting, stored in nonvolatile W 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 affecting the stored setting. Wiper-control of the N57M5114 is accomplished with three input control pins, CS, U/D, and INC. The INC input increments the wiper TSSOP8 TDFN8 VP2 SUFFIX Y SUFFIX in the direction which is determined by the logic state of the U/D input. CASE 511AK CASE 948AL The CS input is used to select the device and also store the wiper position prior to power down. The digital POT can be used as a three-terminal resistive divider or as a two-terminal variable resistor. Digital POTs bring variability and PIN CONFIGURATIONS programmability to a wide variety of applications including control, 1 parameter adjustments, and signal processing.
