Each channel provides 256 wiper tap positions with a linear taper characteristic, controlled over an I²C interface with a selectable address so multiple DS3901E+ devices can share the same bus. The wiper position is stored in non-volatile memory, meaning the setting survives a power cycle — useful for calibration constants or trim values that should not need reloading at every power-up. The typical temperature coefficient of 50 ppm/°C is tight enough that the resistance drift across the full temperature span stays within the ±20% tolerance band for most trim and adjustment uses. ## Package and footprint The supplier device package code is 14-TSSOP — same mechanical outline as the generic TSSOP-14. No exposed pad, so thermal dissipation is through the leads only; for continuous operation near the 95°C upper limit, keep the load current modest. ## Lifecycle and compliance The part is ROHS3 compliant, meeting the current EU restriction standard without exemptions.","metaTitle":"Maxim DS3901E+ digital potentiometer, 256 taps, I²C","metaDescription":"Maxim DS3901E+ digital potentiometer IC with three independent linear-taper channels (20k/30k/50k), 256 taps, I²C interface, non-volatile memory.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Taper":"Linear","Package":"Tube","Features":"Selectable Address","Interface":"I²C","Tolerance":"±20%","Memory Type":"Non-Volatile","Configuration":"Potentiometer","Mounting Type":"Surface Mount","Number of Taps":"256","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.4V ~ 5.5V","Resistance (Ohms)":"20k, 30k, 50k","Number of Circuits":"3","Operating Temperature":"-40°C ~ 95°C","Supplier Device Package":"14-TSSOP","Temperature Coefficient (Typ)":"50ppm/°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.37000","currency":"USD"},{"qty":10,"price":"$3.02900","currency":"USD"},{"qty":25,"price":"$2.86320","currency":"USD"},{"qty":100,"price":"$2.48160","currency":"USD"},{"qty":250,"price":"$2.35432","currency":"USD"},{"qty":500,"price":"$2.11252","currency":"USD"},{"qty":1000,"price":"$1.78164","currency":"USD"},{"qty":2500,"price":"$1.69256","currency":"USD"},{"qty":5000,"price":"$1.62893","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/DS3901.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the available resistance options for DS3901E+?","answer":"The DS3901E+ contains three independent potentiometer channels with different resistance values: one 20 kΩ, one 30 kΩ, and one 50 kΩ.
