It is configured as a potentiometer (voltage divider) and uses a parallel interface for wiper control. The volatile memory means the wiper position resets to mid-scale on power-up. Typical applications include gain and offset adjustment in industrial sensors, programmable voltage references, and calibration trims in test equipment where a small number of discrete steps is acceptable. ## 4 taps — what that means for your circuit With 4 taps, this part gives four discrete wiper positions. That is coarse adjustment — fine for selecting a fixed gain range or a calibration trim step. ## Supply flexibility: single 5V or dual ±5V The MAX5421CEUB+ runs from a single 5V supply or dual ±5V rails. The dual-supply option lets the wiper swing through bipolar signals, which is useful for op-amp offset nulling or programmable gain amplifiers that need to center around ground. If you only have a single 5V rail, the part works fine — just tie VSS to ground. The 5V logic interface is compatible with standard 5V CMOS and TTL levels. ## Package and footprint Housed in a 10-pin uMAX/uSOP package (3.00 mm body width), this is a surface-mount part that fits tight PCB layouts. The supplier device package is 10-uMAX/uSOP. ## Temperature grade and environment Rated for -40°C to 85°C, this part covers industrial control cabinets, outdoor telecom enclosures, and automotive cabin environments. ## Lifecycle and sourcing It is ROHS3 compliant. No direct pin-compatible second source is listed in the available documentation.","metaTitle":"MAX5421CEUB+ Digital Potentiometer, 15kΩ, 4-Tap, Linear","metaDescription":"MAX5421CEUB+ digital potentiometer from Analog Devices. 15kΩ resistance, 4 taps, linear taper, parallel interface, 5V/±5V supply, -40°C to 85°C, 10-uMAX","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Taper":"Linear","Package":"Tube","Interface":"Parallel","Memory Type":"Volatile","Configuration":"Potentiometer","Mounting Type":"Surface Mount","Number of Taps":"4","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"5V, ±5V","Resistance (Ohms)":"15k","Number of Circuits":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"10-uMAX/uSOP","Resistance - Wiper (Ohms) (Typ)":"500"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.99","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.99000","currency":"USD"},{"qty":10,"price":"$3.58200","currency":"USD"},{"qty":25,"price":"$3.38600","currency":"USD"},{"qty":100,"price":"$2.93460","currency":"USD"},{"qty":250,"price":"$2.78408","currency":"USD"},{"qty":500,"price":"$2.49814","currency":"USD"},{"qty":1000,"price":"$2.10686","currency":"USD"},{"qty":2500,"price":"$2.00152","currency":"USD"},{"qty":5000,"price":"$1.92627","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/49585529ca6ba31fd949515002f5903f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the taper of MAX5421CEUB+?","answer":"The MAX5421CEUB+ has a linear taper, meaning the resistance between the wiper and each end terminal changes linearly with the tap position."},{"question":"Is MAX5421CEUB+ compatible with 5V logic?","answer":"Yes, the parallel interface operates from a 5V supply, making it compatible with standard 5V CMOS and TTL logic levels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5421CEUB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5421CEUB when reusing this data.
