It stores the wiper position in non-volatile memory, so the setting is retained after power is removed — useful for calibration trims, offset nulling, or volume control in equipment that must remember its state at next power-on. The 100-tap resolution gives roughly 100 Ω per step, fine enough for most analog trimming tasks where a mechanical trimmer would drift or need manual adjustment. ## Supply rails and temperature range Runs from a 2.7 V to 5.5 V supply, so it works directly on a 3.3 V or 5 V rail without a separate regulator. The -40°C to 85°C operating range covers industrial environments — factory automation, outdoor telecom, and test equipment — but not under-hood automotive or extended high-temp zones. The 750 ppm/°C temperature coefficient on the end-to-end resistance is typical for a CMOS digital pot; if the application needs tight tracking across temperature, budget for that drift in the system error budget. ## Package and rework considerations Housed in an 8-pin uMAX/uSOP (3 mm body width), the DS1804U-010+ is a small-outline surface-mount part. The 0.118-inch (3.00 mm) width package is fine for hand rework with a hot-air station — the leads are visible and accessible. No exposed pad, so no thermal-via stitching needed. Standard MSL 3 handling applies: bake before reflow if the moisture-barrier bag has been open past the floor-life window. ## Interface and control Controlled via a 3-wire up/down interface: Chip Select (CS), Increment (INC), and Up/Down (U/D). This is a simple serial protocol — no I²C or SPI overhead — so any microcontroller with spare GPIOs can drive it. The wiper moves one tap per INC pulse when CS is low; the direction is set by the U/D pin level. This interface style is common in panel-trim applications where a pushbutton or encoder replaces a pot knob. ## Lifecycle and sourcing The DS1804U-010+ is listed as Active on the manufacturer's status and is ROHS3 compliant. No last-time-buy or end-of-life notice has been issued. For dual-sourcing or a pin-compatible alternate, the DS1804U-050+ (50 kΩ version) shares the same package and pinout — the only difference is the resistance value, so the 10 kΩ variant is the one for this BOM line.","metaTitle":"DS1804U-010+ Digital Potentiometer, 10kΩ, 100 Taps","metaDescription":"DS1804U-010+ 10kΩ digital pot with 100 taps, linear taper, non-volatile memory. 2.7V–5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Taper":"Linear","Package":"Tube","Interface":"Up/Down (U/D, INC, CS)","Tolerance":"±20%","Memory Type":"Non-Volatile","Configuration":"Potentiometer","Mounting Type":"Surface Mount","Number of Taps":"100","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Resistance (Ohms)":"10k","Number of Circuits":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-uMAX/uSOP","Temperature Coefficient (Typ)":"750ppm/°C","Resistance - Wiper (Ohms) (Typ)":"400"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.41","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.41000","currency":"USD"},{"qty":10,"price":"$4.85600","currency":"USD"},{"qty":25,"price":"$4.59040","currency":"USD"},{"qty":100,"price":"$3.97840","currency":"USD"},{"qty":250,"price":"$3.77436","currency":"USD"},{"qty":500,"price":"$3.38674","currency":"USD"},{"qty":1000,"price":"$2.85628","currency":"USD"},{"qty":2500,"price":"$2.71346","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/56d895d291ba13a030ade422b65102e0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DS1804U-010+ work with 3.3V?","answer":"Yes, the supply range is 2.7 V to 5.5 V, so it runs directly from a 3.3 V rail without a separate regulator."},{"question":"What is the difference between DS1804U-010+ and DS1804U-050+?","answer":"The DS1804U-010+ is a 10 kΩ device; the DS1804U-050+ is 50 kΩ.
