Temperature coefficient is 35 ppm/°C typical, so a 100 kΩ resistance drifts about 3.5 Ω per °C — negligible for gain trimming but relevant if the pot sets a precision threshold across temperature. Tolerance is ±25 % — the absolute resistance of each channel can vary by up to 25 kΩ from nominal; the ratiometric accuracy (tap-to-tap linearity) is tighter and is what matters for divider applications. ## Supply rails, memory type, and bus addressing Memory type is volatile — the wiper position resets to mid-scale on power-up and is lost when the supply drops below the minimum operating voltage. The I2C interface supports a selectable address pin, allowing up to two devices on the same bus without an address conflict.","metaTitle":"MAX5387NAUD+T 100k 256-Tap Dual Digital Potentiometer, I2C","metaDescription":"MAX5387NAUD+T dual 100k digital potentiometer, 256 taps, I2C interface, 14-TSSOP.
