Frequently Asked Questions
How many wiper positions does the MCP4631-103E/ST provide, and what resistance range does that cover?
The MCP4631-103E/ST offers 129 wiper positions across its 10 kohm end-to-end resistance, delivering fine-grained software control of resistance values from near 0 ohm to 10 kohm for use in programmable gain, trimming, and analog adjustment circuits.
Which communication interface does the MCP4631-103E/ST use, and how fast is it?
The MCP4631-103E/ST uses a 2-wire I2C serial interface with a nominal signal bandwidth of 2 kHz, allowing any I2C-capable microcontroller to set wiper positions digitally without requiring SPI or dedicated analog control signals.
In which types of audio or industrial designs does a dual-channel 10 kohm digital pot provide the most value?
Dual-channel devices like the MCP4631-103E/ST are ideal for stereo audio volume control, differential signal attenuation, and two-axis sensor calibration applications where matching 10 kohm channels must be adjusted simultaneously in software, reducing manual trimmer components on the PCB.
