Its headline draw is 1.5µA supply current — low enough that the reference itself doesn't dominate the power budget in a battery-powered sensor node or portable instrument that stays on continuously. Input range spans 4.596V to 18V, so it runs from a 5V rail with 0.4V headroom or straight off a 12V supply without a pre-regulator. The 5 mA output current is enough to drive an ADC reference input and its decoupling capacitor without an external buffer. ## Noise floor and temperature drift — what the numbers mean on the bench For a 4.096V output, that works out to roughly 123 µVp-p — relevant when the reference feeds a 16-bit or 18-bit ADC where the LSB at 4.096V full-scale is 62.5 µV or 15.6 µV respectively. The noise sits below the LSB for 16-bit conversions but starts to eat into the noise budget at higher resolutions. Over a 125°C span, the output drifts by up to 5.12 mV — about 0.125% of the 4.096V set point. That's tight enough for 12-bit absolute accuracy across temperature but needs calibration for 16-bit systems that hold accuracy over the full temperature window. ## Package, mounting, and board integration The 6-WFDFN exposed pad package measures 2x2 mm (supplier device package 6-DFN). The exposed pad on the underside must be soldered to a PCB thermal land — it carries the ground connection and pulls heat out of the die. Without a proper thermal via array under the pad, the junction temperature rises faster than the datasheet's thermal resistance assumes. ## Lifecycle and compliance — active, no obsolescence concern ROHS3 compliant per the manufacturer's declaration.","metaTitle":"LT6656AIDC-4.096#TRMPBF Voltage Reference, 4.096V ±0.1%","metaDescription":"Analog Devices LT6656AIDC-4.096#TRMPBF precision series voltage reference, 4.096V output, ±0.1% tolerance, 1.5µA supply current, 6-DFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-WFDFN Exposed Pad","Reference Type":"Series","Voltage - Input":"4.596V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"5 mA","Current - Supply":"1.5µA","Noise - 0.1Hz to 10Hz":"30ppmp-p","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"6-DFN (2x2)","Temperature Coefficient":"10ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.13","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.13000","currency":"USD"},{"qty":10,"price":"$8.25000","currency":"USD"},{"qty":25,"price":"$7.86640","currency":"USD"},{"qty":100,"price":"$6.83020","currency":"USD"},{"qty":250,"price":"$6.52324","currency":"USD"},{"qty":500,"price":"$5.94766","currency":"USD"},{"qty":1000,"price":"$5.43000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4da6b5e6e61f1845ca28a660763bd7ba.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source — ADR3440ARJZ-R2?","answer":"The pinout and footprint differ — a board spin is required to swap between them."},{"question":"What is LT6656AIDC-4.096#TRMPBF's listed tolerance?","answer":"Initial output voltage tolerance is ±0.1% at 25°C."},{"question":"What compliance documentation does Analog Devices provide for LT6656AIDC-4.096#TRMPBF?","answer":"The part is ROHS3 compliant per the manufacturer's listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT6656AIDC-4.096~4TRMPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT6656AIDC-4.096~4TRMPBF when reusing this data.
