It communicates over an I²C interface and operates from a 1.7V to 5.5V supply, covering 1.8V, 3.3V, and 5V logic rails. The 16-TSSOP package fits surface-mount assembly, and the -40°C to 125°C temperature range suits industrial and automotive environments where the board sees thermal cycling or under-hood heat. ## Package and mounting 256 taps per channel give 50kΩ / 256 ≈ 195Ω per step, which is fine enough for most trim and level-setting jobs — volume controls, filter tuning, or programmable references. The linear taper means wiper resistance changes linearly with digital code, so you get equal increments across the range. Wiper resistance is 200Ω max (typical 200Ω), which matters when you are setting a low-impedance divider; budget that series resistance into your calculation. The 35ppm/°C temperature coefficient is tight enough that the set point does not drift noticeably across the -40°C to 125°C range — good for an adjustable regulator feedback divider or a sensor bias network that needs to stay put. The ±25% tolerance on the total resistance is typical for digital pots — the absolute value varies part-to-part, but the ratiometric accuracy between taps is much better. If you need a precise absolute resistance, plan a calibration step or use the pot in a divider where the ratio, not the absolute value, sets the output. The memory type is volatile, so the wiper resets to mid-scale on every power-up. That is fine for a volume control or a one-time calibration stored in an external EEPROM, but not for a trim that must hold its value across power cycles without a host writing it back. ## Supply voltage and I²C bus compatibility The 1.7V to 5.5V supply range means this part works on a 3.3V rail directly — no extra level shifter needed. The I²C interface includes a selectable address feature (pin-strapped), so you can put up to two of these on the same bus without conflict. The wide supply also covers 1.8V and 5V logic, which makes it a handy single part to stock for mixed-voltage boards. ## Lifecycle and sourcing reality The MAX5392MAUE+ is listed as Active and ROHS3 compliant.","metaTitle":"MAX5392MAUE+ 50kΩ 256-Tap I²C Digital Potentiometer","metaDescription":"MAX5392MAUE+ dual 50kΩ linear digital pot with 256 taps, I²C interface, 1.7V-5.5V supply, -40°C to 125°C.
