Typical accuracy is ±0.5°C from 0°C to 65°C, with a worst-case ±1°C across the full -40°C to 125°C range. That ±0.5°C window is tight enough for thermal-throttle logic in a base station or battery-pack monitoring without a calibration step. Supply voltage spans 1.4V to 3.6V, so it runs directly off a 1.8V or 3.3V rail — no extra LDO needed. ## SOT-563 footprint — board-fit note The supplier device package is SOT-5X3, a 5-lead SOT-563 measuring roughly 1.6 mm x 1.6 mm. The 0.5 mm pitch and exposed pad demand a standard 2-layer PCB with a thermal via under the pad if the sensor is near a heat source. Cut Tape works for prototypes and small runs.","metaTitle":"TMP112BIDRLR Digital Temp Sensor – 12-bit I²C, SOT-563","metaDescription":"Texas Instruments TMP112BIDRLR digital local temp sensor: 12-bit resolution, ±0.5°C accuracy, 1.4V–3.6V supply, SOT-563 package.","metaKeywords":null},"attributes":{"series":"TMP112BI","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"-","Resolution":"12 b","Output Type":"2-Wire Serial, I²C/SMBUS","Sensor Type":"Digital, Local","Mounting Type":"Surface Mount","Package / Case":"SOT-563, SOT-666","Product Status":"Active","Test Condition":"0°C ~ 65°C (-40°C ~ 125°C)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.4V ~ 3.6V","Base Product Number":"TMP112","Operating Temperature":"-40°C~125°C","Supplier Device Package":"SOT-5X3","Accuracy - Highest (Lowest)":"±0.5°C (±1°C)","Sensing Temperature - Local":"-40°C~125°C","Sensing Temperature - Remote":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.41000","currency":"USD"},{"qty":10,"price":"$2.16300","currency":"USD"},{"qty":25,"price":"$2.04040","currency":"USD"},{"qty":100,"price":"$1.73850","currency":"USD"},{"qty":250,"price":"$1.63240","currency":"USD"},{"qty":500,"price":"$1.42836","currency":"USD"},{"qty":1000,"price":"$1.18349","currency":"USD"},{"qty":3000,"price":"$1.15500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7fc8ac1f7aeffc1c6af66a7fd7de6d27.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TMP112BIDRLR equivalent to TMP112AIDRLR?","answer":"Both are in the TMP112 family with the same 12-bit I²C interface and SOT-563 package.
