Each channel offers two distinct resistance ranges: 1.45 kΩ and 2.54 kΩ, with a ±20% tolerance. The 64-tap resolution means the smallest step size is roughly 22.7 Ω on the 1.45 kΩ range — fine enough for audio channel balancing or trimming a feedback divider without external trim pots. ## Supply, temperature, and drift Memory is non-volatile, so the wiper position persists through power cycles — no need for a host microcontroller to re-initialise the pot at every power-up. The I²C interface with a selectable address lets up to eight DS3906U+ devices share the same bus, useful for multi-channel trim or calibration boards.","metaTitle":"DS3906U+ Digital Potentiometer, 64 Taps, I²C, 10-uMAX","metaDescription":"DS3906U+ from Analog Devices: 3-circuit digital rheostat, pseudo-logarithmic taper, 64 taps, I²C interface, non-volatile memory.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Taper":"Pseudo-Logarithmic","Package":"Tube","Features":"Selectable Address","Interface":"I²C","Tolerance":"±20%","Memory Type":"Non-Volatile","Configuration":"Rheostat","Mounting Type":"Surface Mount","Number of Taps":"64","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Resistance (Ohms)":"1.45k, 2.54k","Number of Circuits":"3","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"10-uMAX/uSOP","Temperature Coefficient (Typ)":"60ppm/°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.80000","currency":"USD"},{"qty":10,"price":"$4.30800","currency":"USD"},{"qty":25,"price":"$4.07240","currency":"USD"},{"qty":100,"price":"$3.52950","currency":"USD"},{"qty":250,"price":"$3.34848","currency":"USD"},{"qty":500,"price":"$3.00460","currency":"USD"},{"qty":1000,"price":"$2.71500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9ca37f4f10179c4dbccbaa50593d876e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the pseudo-logarithmic taper mean for my circuit?","answer":"The pseudo-logarithmic taper means the resistance between the wiper and the terminal changes in a logarithmic step pattern across the 64 taps, rather than a linear one.
