It operates from a 4.146 V to 5.5 V input rail and draws 59 µA quiescent supply current. The part is housed in a SOT-23-3 package and rated for -40°C to 125°C, making it suitable for industrial sensor interfaces, ADC reference biasing, and precision comparator circuits where board space is tight. ## 25 mA output — load budget check The 25 mA output current is the maximum the reference can source. ## Active, available, no LTB watch The REF2940AIDBZR carries an Active product status and is ROHS3 compliant.","metaTitle":"TI REF2940AIDBZR Voltage Reference, 4.096 V Fixed, ±2%","metaDescription":"Texas Instruments REF2940AIDBZR series voltage reference, 4.096 V fixed output, ±2% tolerance, 25 mA output, SOT-23-3, active production.","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":"±2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Series","Voltage - Input":"4.146V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"59µA","Noise - 0.1Hz to 10Hz":"45µVp-p","Noise - 10Hz to 10kHz":"128µVrms","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.35","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.35000","currency":"USD"},{"qty":10,"price":"$1.20500","currency":"USD"},{"qty":25,"price":"$1.14320","currency":"USD"},{"qty":100,"price":"$0.93910","currency":"USD"},{"qty":250,"price":"$0.87788","currency":"USD"},{"qty":500,"price":"$0.77580","currency":"USD"},{"qty":1000,"price":"$0.61247","currency":"USD"},{"qty":3000,"price":"$0.57780","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e9ad5b6a3b8d29039572b3f63723876a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can REF2940AIDBZR be used as a replacement for REF2940AIDBZT?","answer":"The REF2940AIDBZR and REF2940AIDBZT share the same electrical specifications and SOT-23-3 package. The difference is the shipping medium — Tape & Reel vs. Cut Tape. Electrically they are identical, so the BZR variant can replace the BZT in the same design."},{"question":"When sourcing REF2940AIDBZR, what's the closest functional second-source — LM4132AMF-4.1/NOPB?","answer":"The LM4132AMF-4.1/NOPB is a higher-precision series reference with ±0.05% tolerance and 20 ppm/°C drift, compared to the REF2940AIDBZR's ±2% and 100 ppm/°C. Both are 4.096 V fixed outputs in SOT-23-3 packages, but the LM4132 is a tighter-grade part for applications requiring better accuracy. The REF2940AIDBZR is the cost-optimized option for designs that can tolerate ±2% initial error."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF2940AIDBZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF2940AIDBZR when reusing this data.
