Key Features
- Single-channel digital potentiometer with 100 kΩ end-to-end resistance
- 129-position linear wiper for precise resistance tuning over SPI
- Increment/decrement SPI interface for simple one-wire step control
- Non-volatile wiper position memory retains setting across power cycles
- 8-pin PDIP package for through-hole prototyping and easy lab evaluation
Applications
The MCP4141-104E/P is used in analog circuit calibration, programmable gain amplifier designs, and volume control circuits where software-controlled resistance adjustment is preferred over mechanical trimmers. Its SPI increment/decrement control allows a microcontroller to step the wiper through 129 positions to achieve fine resistance tuning in audio equipment, sensor conditioning stages, and industrial process control systems. The non-volatile wiper memory ensures settings are retained after power-off without requiring reprogramming on each startup.

Frequently Asked Questions
How many resistance steps does MCP4141-104E/P provide and how does the SPI interface control it?
The MCP4141-104E/P offers 129 wiper positions across a 100 kΩ end-to-end resistance, yielding approximately 775 Ω per step. Wiper movement is controlled via an SPI increment/decrement command interface, allowing a microcontroller to step the resistance up or down one position at a time without requiring absolute address writes.
Does MCP4141-104E/P retain its wiper position after power is removed?
Yes, the MCP4141-104E/P includes non-volatile memory that stores the wiper position across power cycles. When the device is powered on, it restores the last saved 100 kΩ position setting automatically, eliminating the need for a microcontroller to recalibrate or reinitialize the potentiometer value on every startup.
What procurement and form-factor considerations apply when using MCP4141-104E/P in volume production?
The MCP4141-104E/P is available in an 8-pin PDIP through-hole package with a factory lead time of approximately 8 weeks and a YTEOL of 9 years. Designers targeting SMT mass production should evaluate the MCP4141 SOIC-8 or MSOP-8 variants to reduce per-unit assembly cost and improve placement density on high-volume PCBs.
