Key Features
- Dual-channel 50 kΩ resistance with 129 wiper positions for fine-resolution analog control
- SPI-compatible serial increment/decrement interface minimizes microcontroller pin usage
- Non-volatile EEPROM retains wiper position through power cycles without firmware re-initialization
- 200 Hz bandwidth suited for low-frequency signal conditioning and precision trim applications
- 14-pin PDIP package allows direct breadboard or through-hole soldering for prototyping
Applications
MCP4241-503E/P is used in low-frequency filter tuning, precision analog gain adjustment, and sensor offset calibration circuits where two independent 50 kΩ channels with memory are required. Its non-volatile wiper storage makes it popular in field-calibrated instruments, medical device parameter adjustment, and industrial control systems where setting retention after power loss is mandatory.

Frequently Asked Questions
How fine is the resistance resolution of MCP4241-503E/P across its 50 kΩ range?
MCP4241-503E/P provides 129 wiper positions across 50 kΩ, giving a step size of approximately 390 Ω per increment. This resolution supports precision trim, analog gain adjustment, and filter frequency tuning in circuits where 1% or better resistance accuracy is required.
Does MCP4241-503E/P retain its resistance setting if the board loses power unexpectedly in a field instrument?
Yes. MCP4241-503E/P stores each channel's wiper position in on-chip non-volatile EEPROM, so both 50 kΩ settings are preserved through power interruptions and restored automatically on power-up without any firmware initialization routine.
What SPI signal lines are needed to control MCP4241-503E/P from a standard microcontroller?
MCP4241-503E/P uses a 3-wire SPI-compatible interface — chip select (CS), clock (SCK), and data (SDI/SDO) — requiring only 3 microcontroller pins to control both potentiometer channels. Commands include increment, decrement, and direct wiper register write across a supply range of 1.8 V to 5.5 V.
What lead time and typical order quantity should procurement expect for MCP4241-503E/P?
Factory lead time for MCP4241-503E/P is approximately 8 weeks from Microchip authorized distributors. Production engineers building 500 or more units should place orders at least 10 weeks ahead; small prototype quantities of under 50 units are often available from distributor stock with shorter 1-2 week delivery.
