The linear taper suits level-setting and trim applications where the wiper resistance is a consistent 75 Ω typical across the range. The 150 ppm/°C tempo means the 10 kΩ end-to-end resistance drifts about 150 Ω over a 100°C swing — something to budget if the pot sets a precision bias. The selectable address feature lets you hang up to four of these on the same I²C bus by tying the address pins high or low — handy for multi-channel trim boards without extra GPIOs.","metaTitle":"MCP4531-103E/MS Digital Potentiometer, 10kΩ, 129 Taps, I²C","metaDescription":"Microchip MCP4531-103E/MS digital potentiometer, 10kΩ, 129 taps, I²C, ±20% tolerance, -40°C to 125°C.
