With a supply current of 750 µA at either 3.3 V or 5 V, it adds negligible load to the I²C rail — important for power-budgeted designs where every microamp counts. ## Supply voltage flexibility and temperature grade Rated for both 3.3 V and 5 V supply rails, the DS2482S-800+T&R bridges systems where the I²C master runs at one voltage and the 1-Wire bus needs the other — no external level shifter required. ## Active lifecycle — no end-of-life risk ROHS3 compliant — no exemption-based solder restrictions.","metaTitle":"DS2482S-800+T&R – Analog Devices 1-Wire to I²C Bridge IC","metaDescription":"DS2482S-800+T&R from Analog Devices: 1-Wire to I²C bridge, 8-channel, 3.3V/5V supply, 750 µA supply current, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Bridge, 1-Wire® to I²C","Protocol":"1-Wire®","Interface":"I²C","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"750µA","Voltage - Supply":"3.3V, 5V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.82000","currency":"USD"},{"qty":10,"price":"$9.77200","currency":"USD"},{"qty":25,"price":"$9.31720","currency":"USD"},{"qty":100,"price":"$8.09010","currency":"USD"},{"qty":250,"price":"$7.72648","currency":"USD"},{"qty":500,"price":"$7.04476","currency":"USD"},{"qty":1000,"price":"$6.13575","currency":"USD"},{"qty":2500,"price":"$5.90850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/978920eb98631bc34f738858dc077677.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DS2482S-800+T&R compatible with both 3.3V and 5V systems?","answer":"Yes — the voltage supply range covers both 3.3 V and 5 V. The I²C interface operates at the supply voltage; the 1-Wire bus can be driven at the same level or with an external pull-up resistor to a different rail, depending on the 1-Wire slave requirements."},{"question":"How many 1-Wire devices can be connected to one DS2482S-800+T&R?","answer":"The DS2482S-800+T&R supports up to eight 1-Wire devices on a single bus (implied by the '8CH' in the description,). The practical limit depends on cable length and parasitic capacitance — for long runs, a 1-Wire repeater or shorter stub lengths may be needed."},{"question":"What is the difference between DS2482S-800+T&R and DS2482S-800+?","answer":"The DS2482S-800+T&R is the tape-and-reel (T&R) packaging variant of the DS2482S-800+ (tube). The electrical function, pinout, and package (16-SOIC) are identical. The T&R suffix is for automated pick-and-place assembly."},{"question":"What is the maximum cable length for 1-Wire with DS2482S-800?","answer":"The evidence does not specify a maximum cable length. In practice, 1-Wire networks with the DS2482S-800 can run up to 100–300 meters depending on wire gauge, number of devices, and data rate, but this is application-specific and not guaranteed by the datasheet alone."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS2482S-800TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS2482S-800TR when reusing this data.
