The I²C interface handles both channels over a two-wire bus, with a selectable address so up to four devices share the same bus without address conflicts — useful in multi-channel calibration boards. Non-volatile memory retains the wiper position at power-off — no need to re-initialise the trim after a power cycle, which matters for set-and-forget adjustments like bias voltages or sensor offsets. The 70ppm/°C typical temperature coefficient means the resistance drifts about 7Ω per °C at the 100kΩ end — negligible for most divider applications but worth budgeting in a precision reference. Wiper resistance is 325Ω typical — the series resistance between the wiper terminal and the internal tap point. At the low end of the divider this adds a small offset; factor it into the end-stop voltage calculation. ## 14-TSSOP package — board-fit notes Housed in a 14-TSSOP with 0.173-inch (4.40mm) body width — the standard thin-shrink SOP footprint. Supplied in Tube — the standard antistatic shipping format for prototype and low-volume builds. For reel packaging check the alternate order code suffix.","metaTitle":"MAX5479EUD+ Dual 100kΩ Digital Potentiometer, 256 Taps","metaDescription":"MAX5479EUD+ from Analog Devices: dual 100kΩ digital potentiometer, 256 taps, I²C interface, non-volatile memory.
