On a dead board, if you see a scorch mark near the can, the part probably survived; the supply rail or the ADC input that reads it is what actually died. The output is a linear analog voltage at 10mV/°C — no I2C, no SPI, just a DC level you can read with a meter or an ADC pin. At 25°C the output sits at 250 mV; at 150°C it's 1.5 V. That scale factor means you don't need a lookup table or calibration constants in firmware. ## Accuracy across the temperature span That ±1.5°C is the number to budget for in a thermal-shutdown circuit or an oven controller — the typical figure is what the datasheet guarantees at room temp, but the hot-end tolerance is wider. The supply voltage range is 4V to 30V, so the same part works on a 5V logic rail or a 24V industrial loop. The output impedance is low enough to drive a meter directly, but for an ADC input, a 100 nF bypass cap at the supply pin and a 1 kΩ series resistor on the output clean up any noise picked up on long wires.","metaTitle":"LM35H/NOPB Texas Instruments Analog Temp Sensor, TO-46-3","metaDescription":"LM35H/NOPB precision centigrade temperature sensor, 10mV/°C scale factor, ±1°C accuracy, -55°C to 150°C range, TO-46-3 metal can.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Series":"-","Features":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Resolution":"10mV/°C","Output Type":"Analog Voltage","Part Status":"Active","Sensor Type":"Analog, Local","Manufacturer":"Texas Instruments","Mounting Type":"Through Hole","Package / Case":"TO-206AB, TO-46-3 Metal Can","Test Condition":"25°C (150°C)","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 30V","Base Product Number":"LM35","Operating Temperature":"-55°C ~ 150°C","Supplier Device Package":"TO-46-3","Accuracy - Highest (Lowest)":"±1°C (±1.5°C)","Sensing Temperature - Local":"-55°C ~ 150°C","Sensing Temperature - Remote":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/108b675d57c494c1f6b8d7ac9d60c848.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output scale factor of the LM35H/NOPB?","answer":"The output is linear analog voltage at 10mV/°C.
