What are the key features of MCP4361-104E/ST?
- 4 independent digital potentiometer channels in one 20-pin TSSOP package
- 256 wiper positions for fine-grained resistance control per channel
- 100 kOhm total end-to-end resistance for broad voltage divider applications
- 3-wire SPI serial interface for easy MCU integration
- Non-volatile wiper position storage for power-off state retention
- Low supply voltage operation for 3.3 V and 5 V embedded systems
What is MCP4361-104E/ST used for?
The MCP4361-104E/ST enables software-controlled gain, attenuation, and bias voltage adjustment in analog signal chains without mechanical trimmers. It is commonly used in programmable amplifier gain stages, LCD bias voltage control, and closed-loop calibration circuits where 4 channels of 256-step adjustment provide fine-grained control from a single SPI bus. Industrial sensor conditioning and audio processing boards also use this device to replace multiple fixed resistors with digitally adjustable equivalents.

Frequently Asked Questions
How many adjustment steps and what maximum resistance does the MCP4361-104E/ST provide per channel?
Each of the 4 potentiometer channels in the MCP4361-104E/ST offers 256 discrete wiper positions across a 100 kOhm end-to-end resistance, resulting in approximately 391 ohms per step. This resolution is suitable for precision gain trimming and bias voltage setting in analog circuits where fine incremental adjustment is required without mechanical pots.
Which embedded control bus does the MCP4361-104E/ST use and how many channels can one device handle?
The MCP4361-104E/ST communicates via a 3-wire SPI interface and integrates 4 independent digital potentiometer channels in a single 20-pin TSSOP package. This allows an MCU to control 4 separate resistance values using a shared SPI bus with individual chip select, reducing PCB area and BOM cost compared to using 4 discrete single-channel digital pots.
Can the MCP4361-104E/ST retain its wiper settings after a power cycle in field-calibrated equipment?
Yes, the MCP4361-104E/ST features non-volatile memory that stores the wiper position for all 4 channels across power cycles. This means factory or field calibration values programmed into the device are preserved without MCU intervention at every boot, making it ideal for sensor conditioning boards and measurement instruments that must recall calibration state after power interruption.
