N57M5114WD50TG

Digital Potentiometers Overview

The N57M5114WD50TG is a single-channel digital potentiometer from onsemi, featuring a 50 kΩ resistance value and 32 tap positions. It utilizes an Up/Down serial interface controlled by CS, U/D, and INC pins to adjust the wiper position across a linear taper resistor array. The device incorporates nonvolatile EEPROM memory to retain the wiper setting during power loss, automatically restoring it upon power-up. Operating on a single supply voltage ranging from 2.5 V to 6.0 V, it draws low standby current. The component is housed in an SOIC-8 package with NiPdAu lead finish, designed for industrial temperature ranges.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 50 kΩ nominal resistance
• Non-volatile EEPROM storage retains wiper position after power down
• Up/Down serial interface (CS, U/D, INC) for digital control
• Single supply operation: 2.5 V to 6.0 V with low standby current

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Programmable analog functions such as volume or brightness controls

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the SOIC-8 package and 'D' indicates the 50 kΩ resistance value. Confirm the 'TG' suffix aligns with the required NiPdAu lead finish and RoHS compliance status. Ensure the industrial temperature range rating meets the operational environment requirements before procurement.

Digital Potentiometers Selection Notes

Select this part when a 50 kΩ digital potentiometer with nonvolatile memory is required. The SOIC-8 package is suitable for surface mount applications where space allows. Verify that the system logic levels are compatible with the CMOS input thresholds defined for the 2.5 V to 6.0 V supply range. Consider the 32-tap resolution if finer adjustment steps are not necessary.

Digital Potentiometers Part Context

This component belongs to the N57M5114 family of 32-tap digital potentiometers. Other variants in the series include 10 kΩ and 100 kΩ resistance options, available in MSOP, TSSOP, and TDFN packages. The WD50TG designation specifically identifies the 50 kΩ version in the SOIC-8 package with industrial temperature grading and specific lead finish.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include N57M5114ZD50TG (MSOP-8), N57M5114YD50TG (TSSOP-8), and N57M5114VP2D50TG (TDFN-8). These share identical electrical characteristics and pinouts but differ in physical package dimensions. Cross-package substitution requires PCB footprint verification.
