Key Features
- Four independent 5 kΩ potentiometer channels with 257 wiper positions each for precise analog control
- SPI 3-wire serial interface allows all 4 channels to be addressed from a single SPI bus
- Non-volatile EEPROM stores wiper positions for all 4 channels through power cycles
- 2 kHz bandwidth per channel supports audio and low-frequency signal conditioning applications
- 20-pin QFN package integrates 4 potentiometer channels in a small SMT footprint
Applications
MCP4361-502E/ML is used in multi-axis gain control, stereo audio balance and volume circuits, calibration trim networks for multi-channel sensor arrays, and programmable filter banks where four independent resistance channels are needed in a single package. Its quad-channel SPI-addressable design reduces chip count in industrial instrumentation, medical signal conditioning, and audio processing boards that previously required four discrete digital potentiometers.

Frequently Asked Questions
How many independent resistance channels does MCP4361-502E/ML integrate, and what is the step resolution per channel?
MCP4361-502E/ML integrates 4 independent digital potentiometer channels, each with 257 wiper positions across a 5 kΩ end-to-end resistance. This yields a step size of approximately 19.5 Ω per increment, providing fine-resolution analog control for gain adjustment, filter tuning, and calibration trim in multi-channel systems.
Does MCP4361-502E/ML retain all four channel settings after a power cycle in an instrument that cannot be recalibrated in the field?
Yes. MCP4361-502E/ML stores all 4 channel wiper positions in on-chip non-volatile EEPROM, so every channel's 5 kΩ resistance setting is preserved through power interruptions and restores automatically on the next power-up without any firmware initialization or re-calibration step.
How does the SPI interface of MCP4361-502E/ML scale when controlling multiple quad-potentiometer ICs on the same board?
MCP4361-502E/ML uses a standard 3-wire SPI bus (SCK, SDI, CS) with a unique chip-select per device. Multiple MCP4361 ICs can share the same SCK and SDI lines, with each device selected by its own CS pin. A microcontroller managing 4 devices controls up to 16 potentiometer channels using only 7 GPIO pins total — 2 shared SPI lines plus 4 individual CS lines plus ground.
What lead time and package form factor should buyers confirm when ordering MCP4361-502E/ML for SMT assembly?
Factory lead time for MCP4361-502E/ML is approximately 5 weeks from Microchip authorized distributors. The part ships in a 20-pin QFN package with 0.5 mm pitch, which requires fine-pitch SMT assembly capability. Buyers should confirm reel or tube packaging with their distributor and verify the PCB stencil aperture matches the QFN-20 land pattern recommended in the datasheet.
