That 2.048V level is a natural fit for bipolar ADC ranges — a 0-to-2.048V input maps cleanly to a 12-bit converter's 0.5 mV LSB without scaling resistors. ## Noise and load drive — what the numbers mean for your signal chain For a 16-bit converter with a 2.048V reference, that noise contributes less than 1 LSB of uncertainty at the LSB size of 31.25 µV. The part can source or sink up to 10 mA of output current. That is enough to drive multiple ADC reference inputs or a small buffer stage without loading the reference voltage. Supply current draw is 725 µA typical, so the reference's own power consumption stays well below the signal-chain budget. The series topology means the output tracks the input as long as the input stays above 2.7V plus dropout. ## Package, footprint, and field-swap reality Pin 1 orientation is marked by a notch on the package body — visible under a desk lamp, so you can orient it without a magnifier on a rework bench. Supplied in a tube — not tape-and-reel. For a prototype run or a rework kit, the tube keeps the parts aligned and ESD-safe. No moisture-sensitive-bake required unless the tube seal has been broken for months in a humid environment. RoHS3 compliant.","metaTitle":"MAX6126BASA21+ voltage reference 2.048V ±0.06% SOIC-8","metaDescription":"Analog Devices MAX6126BASA21+ series voltage reference, fixed 2.048V output, ±0.06% tolerance, 10ppm/°C drift, 1.3µVp-p noise, SOIC-8.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Tolerance":"±0.06%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Reference Type":"Series","Voltage - Input":"2.7V ~ 12.6V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"725µA","Noise - 0.1Hz to 10Hz":"1.3µVp-p","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-SOIC","Temperature Coefficient":"10ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.86","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.86000","currency":"USD"},{"qty":10,"price":"$7.10100","currency":"USD"},{"qty":25,"price":"$6.77040","currency":"USD"},{"qty":100,"price":"$5.87880","currency":"USD"},{"qty":250,"price":"$5.61460","currency":"USD"},{"qty":500,"price":"$5.11918","currency":"USD"},{"qty":1000,"price":"$4.45864","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6126BASA21+ pin compatible with MAX6126AESA21+?","answer":"Both parts share the same 8-pin SOIC package and pinout — the BASA21+ and AESA21+ differ only in the temperature range grade. The BASA21+ is the industrial-temperature variant (-40°C to +125°C), while the AESA21+ covers the extended-industrial range. They swap directly on the same PCB footprint."},{"question":"Does MAX6126BASA21+ require any external components for stability?","answer":"As a series reference, the MAX6126BASA21+ is internally compensated and stable with a 1 µF ceramic output capacitor. No external resistor divider or feedback network is needed — the output is fixed at 2.048V. A 0.1 µF bypass cap at the input pin is good practice for noise rejection from the supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6126BASA21~3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6126BASA21~3 when reusing this data.
