Key Features
- Dual-channel 7-bit digital potentiometer with 128 wiper positions and 100 kOhm (104) end-to-end resistance, controllable via SPI interface
- Non-volatile wiper position storage retains resistance settings through power cycles, eliminating initialization routines in embedded calibration applications
- Increment/decrement and direct-access SPI command modes in a compact SOIC-14 package supporting supply voltages from 1.8 V to 5.5 V
Applications
The MCP4241-104E/SL is used for programmable gain control, offset adjustment, and electronic calibration in precision analog front ends, audio equipment, and industrial sensor conditioning circuits. Its dual-channel design with 128 steps per channel allows independent control of two analog parameters over SPI from a single MCU chip-select line. Non-volatile memory makes it ideal for factory calibration of sensors and instrumentation where resistance settings must survive power interruptions.

Frequently Asked Questions
How many resistance steps does MCP4241-104E/SL provide, and what is the step resolution for the 100 kOhm version?
The MCP4241-104E/SL offers 128 wiper positions (7-bit resolution) across a 100 kOhm end-to-end resistance, giving a nominal step size of approximately 781 ohms per step. This resolution supports fine-grained control of gain stages, filter cutoff frequencies, and bias currents in analog signal chains operating from 1.8 V to 5.5 V supplies.
Does MCP4241-104E/SL retain its wiper position after power is removed, and why does that matter for calibration?
Yes. MCP4241-104E/SL stores wiper position in on-chip non-volatile (EEPROM) memory rated for at least 100,000 write cycles. In factory calibration workflows, the 100 kOhm resistance setting is trimmed once and saved; the device restores the exact 128-step position on every subsequent power-up without any SPI transaction from the host MCU.
How does MCP4241-104E/SL compare to a mechanical 100 kOhm trimmer in a PCB-mounted volume control application?
Unlike a mechanical trimmer requiring physical access and prone to wiper wear, MCP4241-104E/SL adjusts resistance digitally via a 10 MHz SPI bus from any microcontroller. The 100 kOhm dual-channel device replaces two mechanical trimmers in a 14-pin SOIC footprint, supports automated test-and-calibrate routines, and guarantees position repeatability within ±1 LSB (approximately 781 ohms) over the -40°C to +125°C range.
Can MCP4241-104E/SL be used as a two-wire rheostat as well as a three-terminal potentiometer?
Yes. Each channel of MCP4241-104E/SL can be configured as a variable resistor (rheostat) by connecting only the wiper (W) and one terminal (A or B), or as a full voltage-divider potentiometer using all 3 terminals. In rheostat mode the resistance varies from approximately 75 ohms (wiper resistance) to 100 kOhm across 128 steps, making it suitable for programmable current-limiting and biasing circuits.
