Key Features
- Single-channel 100 kOhm digital potentiometer with 128 wiper steps (0 to 127) providing ~787 Ohm per step resolution for fine analog adjustment
- Non-volatile wiper position storage using EEPROM retains the last set resistance through power cycles, eliminating startup calibration routines
- SPI-compatible increment/decrement and direct-write interface supports simple daisy-chain expansion of multiple devices on a single bus
- Wide 1.8 V to 5.5 V supply voltage range with low 1 µA sleep current for battery-powered calibration and trimming applications
- SOIC-8 package with RoHS-compliant, Pb-free construction for automated assembly and standard pick-and-place compatibility
Applications
The MCP4141-104E/SN is used in audio equipment, sensor calibration circuits, and power supply voltage-adjust loops where a digitally controlled 100 kOhm resistance with 128 steps replaces a manual trimmer potentiometer. Its non-volatile wiper memory ensures that factory-calibrated offsets for ADC reference voltages, op-amp gain stages, or LCD contrast controls are preserved across power cycles without a microcontroller initialization sequence. The device also suits adaptive filter tuning, LCD bias adjustment, and programmable gain amplifier designs in industrial and consumer electronics operating from 1.8 V to 5.5 V.

Frequently Asked Questions
How many resistance steps does the MCP4141-104E/SN provide and what is the step resolution?
The MCP4141-104E/SN offers 128 wiper steps across a 100 kOhm end-to-end resistance, yielding approximately 787 Ohm per step. The wiper resistance itself is typically 75 Ohm, so the minimum achievable resistance between wiper and either terminal is around 75 Ohm to 150 Ohm. This resolution is sufficient for audio volume control, LCD contrast adjustment, and sensor bridge trimming where step changes below 1 kOhm are acceptable.
Does the MCP4141-104E/SN retain its wiper position after power is removed?
Yes. The MCP4141 stores the wiper position in an internal EEPROM, which retains the value through power cycles without any external memory or MCU re-initialization. The EEPROM endurance is rated at 100,000 write cycles and data retention exceeds 40 years, making the device reliable for factory calibration of gain trims and offset adjustments that should not drift between power-on events in field-deployed equipment.
What control interface does the MCP4141-104E/SN use and can multiple devices share one SPI bus?
The device uses an SPI-compatible 3-wire interface (SCK, SDI, CS) supporting increment, decrement, and direct-write commands at clock rates up to several MHz. Multiple MCP4141 devices can be daisy-chained on a shared SPI bus by connecting the SDO output of one device to the SDI input of the next, allowing an MCU to update a chain of 100 kOhm potentiometers with a single CS assertion and sequential 16-bit transfers.
What supply voltage range is required for the MCP4141-104E/SN and does it support 3.3 V MCU logic?
The MCP4141-104E/SN operates from 1.8 V to 5.5 V, making it directly compatible with 3.3 V and 5 V microcontroller I/O without level shifters. At 1.8 V supply, the SPI logic thresholds scale accordingly, so it also works with low-power 1.8 V MCU platforms used in wearables and energy-harvesting nodes. Typical quiescent current is under 1 µA in standby, contributing negligible drain to coin-cell-powered designs.
How does the MCP4141-104E/SN compare to a mechanically trimmed potentiometer in a production calibration workflow?
Unlike a mechanical trimmer requiring physical access and a screwdriver, the MCP4141 accepts calibration commands over the SPI bus from automated test equipment, enabling in-system calibration at the end of a production line without board handling. The 128-step, 100 kOhm resolution replaces a 25-turn cermet trimmer in most gain and offset trim applications, and the non-volatile EEPROM stores the result permanently. This cuts calibration cycle time to under 1 ms per device versus several seconds for manual adjustment.
