Key Features
- 128-step resolution with 5 kOhm end-to-end resistance providing fine-grained analog adjustment via SPI increment/decrement commands
- Non-volatile wiper position storage retaining the last set resistance value after power removal without software overhead
- 2 kHz bandwidth enabling use in audio volume control, tone adjustment, and low-frequency signal conditioning circuits
- Single-supply operation from 1.8V to 5.5V for compatibility with both 3.3V and 5V microcontroller systems
Applications
The MCP4141-502E/SN is used in programmable gain amplifier stages, audio volume controls, and calibration adjustment circuits where software-controlled resistance replaces a manual trimmer potentiometer. Its non-volatile memory makes it ideal for set-and-forget calibration in production-line equipment, eliminating the need for re-calibration after power cycling. Portable instruments and consumer electronics also use it for digitally adjustable LCD contrast, LED brightness, and sensor bias without additional EEPROM chips.

Frequently Asked Questions
How many resistance steps does MCP4141-502E/SN offer, and what end-to-end resistance does it provide?
MCP4141-502E/SN features 128 wiper positions across a 5 kOhm end-to-end resistance, yielding a step size of approximately 39 Ohm per increment. The increment/decrement SPI interface allows the host MCU to adjust resistance in real time at the 2 kHz bandwidth limit of the internal resistor ladder.
Does MCP4141-502E/SN retain its wiper setting after power is removed, and how is that stored?
Yes, MCP4141-502E/SN stores the wiper position in on-chip non-volatile EEPROM that retains data for at least 40 years at +25°C. After power-up the device restores the last saved wiper setting automatically, eliminating initialization code in the host MCU and avoiding startup glitches in audio or bias circuits.
For a 3.3V microcontroller system, what supply voltage range does MCP4141-502E/SN support?
MCP4141-502E/SN operates from a 1.8V to 5.5V single supply, covering both 3.3V and 5V microcontroller systems without level-shifting logic. The SPI interface accepts logic levels proportional to the supply, so a 3.3V MCU interfaces directly to the device without additional translation components.
When is MCP4141-502E/SN a better calibration solution than a mechanical trimmer in production equipment?
MCP4141-502E/SN replaces mechanical trimmers in production calibration when hundreds of units need precise, repeatable resistance settings stored digitally. Automated test equipment can write calibration values via SPI in under 1 ms, cutting calibration time per unit compared to manual trimmer adjustment, while non-volatile storage ensures values survive years of power cycling without drift.
