Key Features
- Non-volatile EEPROM wiper storage retains last resistance position across power cycles without host MCU intervention
- Increment/decrement UP/DOWN/CS pin interface requires only 3 GPIO lines, simplifying microcontroller integration
- Single-channel 50 kOhm with 128 steps provides 391-ohm step resolution in a through-hole PDIP-8 package
Applications
The MCP4141-503E/P suits prototyping, hobbyist circuits, and production designs that benefit from through-hole PDIP-8 assembly, such as audio volume controls, LED dimming circuits, and calibration trim replacements on industrial boards. Its non-volatile wiper memory eliminates factory calibration procedures that would otherwise require power-on programming. Low-volume and prototype boards take advantage of the PDIP footprint for easy breadboard and socket insertion.

Frequently Asked Questions
How does the increment/decrement interface of the MCP4141-503E/P work compared to SPI-based digital potentiometers?
The MCP4141-503E/P uses a 3-wire UP/DOWN/CS hardware interface rather than SPI, where UP and DOWN pulses move the wiper one 391-ohm step per clock edge. This eliminates the need for a full SPI peripheral, letting a microcontroller use any 3 GPIO lines to adjust the 50 kOhm resistance across 128 steps.
What total resistance and step resolution does the MCP4141-503E/P offer for use in audio volume control circuits?
The device provides a 50 kOhm end-to-end resistance divided into 128 equal steps, giving a resolution of approximately 391 ohms per step. For audio volume control, this allows gradual gain adjustment in an inverting op-amp stage where the wiper position sets the feedback ratio, covering a wide attenuation range without audible clicking.
Does the MCP4141-503E/P retain its wiper position when power is removed?
Yes. The wiper position is stored in an on-chip EEPROM, which retains data for at least 100 years at 25°C and survives more than 1 million write cycles. On power-up, the device restores its last saved position automatically, making it suitable for one-time factory calibration of gain or bias circuits without firmware re-programming.
For a replacement of a manual trim-pot in a production board, what supply voltage range does the MCP4141-503E/P support?
The MCP4141-503E/P operates from 1.8 V to 5.5 V, covering common 3.3 V and 5 V system rails. Its wiper resistance is specified over this full range, and the 50 kOhm end-to-end resistance remains within ±20% tolerance across the -40°C to +85°C industrial temperature range, providing reliable trim-pot replacement in industrial control boards.
