Its non-volatile memory retains the wiper position through a power cycle, so the calibration or trim value is present at system power-on without a software reload — a key advantage in set-and-forget analog adjustments like VCO bias or LCD contrast. The part communicates over an I²C interface with a selectable address, allowing multiple DS3501U+ devices on the same bus without address conflicts. ## Supply rails and temperature range This split-supply architecture lets the digital interface run at a lower logic voltage while the analog wiper swings across a wider voltage range — useful when the pot is used as a voltage divider in a higher-voltage signal path. The temperature coefficient is ±4 ppm/°C typical, meaning the resistance drifts less than 0.04% over a 100°C swing. For a 10 kΩ pot, that is under 4 Ω of change — negligible in most precision divider applications. Housed in a 10-TFSOP / 10-MSOP package measuring 3.00 mm wide, with the supplier device package listed as 10-uMAX/uSOP. Supplied in tube packaging; the part is also available in tape-and-reel under a different order code for automated assembly.","metaTitle":"Analog Devices DS3501U+ Digital Pot, 10kΩ, 128-Tap, I²C","metaDescription":"DS3501U+ from Analog Devices: 10kΩ digital potentiometer, 128 taps, linear taper, I²C interface, non-volatile memory, -40°C to 100°C.

Linear taper means the resistance between the wiper and either end changes by the same increment per tap step — no logarithmic curve, so it is a straight choice for voltage-divider or programmable-gain circuits where each step should be a fixed resistance change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS3501U","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS3501U when reusing this data.
