The non-volatile memory retains the wiper setting at power-off, so the part powers up at the last programmed position without host intervention. Operating from a 2.7V to 5.25V supply and rated over -40°C to 85°C, it fits industrial control loops, power-supply trimming, and sensor calibration where the wiper setting must survive a power cycle. ## 256 taps, 325 Ω wiper resistance, 35 ppm/°C tempo Each of the two potentiometers offers 256 tap positions, giving a step size of roughly 39 Ω per tap on the 10kΩ end-to-end resistance. The typical wiper resistance is 325 Ω, which adds a fixed series offset that matters when the pot is used as a voltage divider with a high-impedance load. The ±25% absolute resistance tolerance means the end-to-end value can vary from 7.5 kΩ to 12.5 kΩ. In ratiometric circuits (e.g., a voltage divider feeding an ADC reference) the ratio tracks well, but absolute-resistance-critical designs should plan for a calibration trim. ## Active production, 14-TSSOP package It is ROHS3 compliant and supplied in a 14-lead TSSOP package (4.40 mm body width). No immediate obsolescence risk — the part is a current catalog item from Analog Devices.","metaTitle":"MAX5487EUD+ 10kΩ Linear Digital Potentiometer, 256 Taps, SPI","metaDescription":"MAX5487EUD+ from Analog Devices: 10kΩ dual linear digital potentiometer, 256 taps, SPI interface, non-volatile memory, 2.7V-5.25V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Taper":"Linear","Package":"Tube","Interface":"SPI","Tolerance":"±25%","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":"2.7V ~ 5.25V","Resistance (Ohms)":"10k","Number of Circuits":"2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"14-TSSOP","Temperature Coefficient (Typ)":"35ppm/°C","Resistance - Wiper (Ohms) (Typ)":"325"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.16","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.16000","currency":"USD"},{"qty":10,"price":"$5.52900","currency":"USD"},{"qty":25,"price":"$5.22680","currency":"USD"},{"qty":100,"price":"$4.52980","currency":"USD"},{"qty":250,"price":"$4.29756","currency":"USD"},{"qty":500,"price":"$3.85618","currency":"USD"},{"qty":1000,"price":"$3.25220","currency":"USD"},{"qty":2500,"price":"$3.08959","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/41a988d887f228d971beed3fe4229fa3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the MAX5487EUD+ pin-to-pin compatible with the AD5260?","answer":"The AD5260 is a single-channel 256-tap digital pot from Analog Devices in a 14-TSSOP package. The MAX5487EUD+ is a dual-channel part, so the pinout and register map are different. They are not drop-in replacements. For a single-channel alternative, the MAX5486EUD+ (single 10kΩ, same package) is a closer match."},{"question":"Can I substitute the MAX5487EUD+ with the MCP41010?","answer":"The MCP41010 is a single 10kΩ digital pot with 256 taps and SPI, but it is in an 8-pin DIP/SOIC package and has volatile wiper memory. The MAX5487EUD+ is dual-channel, non-volatile, and in a 14-TSSOP footprint. They are not pin-compatible and the memory type differs — a substitution would require a board spin and firmware change."},{"question":"Is the MAX5487EUD+ compatible with 3.3V logic?","answer":"Yes. The supply range is 2.7V to 5.25V, and the SPI logic thresholds scale with VDD. At a 3.3V supply, the input high threshold is typically 0.7 × VDD ≈ 2.3V, which is met by 3.3V CMOS logic. No level shifter is needed when the host MCU runs at the same rail."},{"question":"Can the MAX5487EUD+ be used for audio volume control?","answer":"The linear taper is not ideal for audio volume because human hearing perceives loudness logarithmically. A logarithmic (audio) taper pot like the MAX5488 (10kΩ, log taper) would give a more natural volume curve. The MAX5487EUD+ can be used in a digitally-controlled gain stage if the linear steps are acceptable or corrected in firmware."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5487EUD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5487EUD when reusing this data.
