每升高1°CZ輸出電壓增加10mVeLM35有多種不同封裝型式,夕卜觀如圖所示。在常溫下,LM35不需要額外的校準處理即可達到±1/4°C的準確率。其電源供應(yīng)模式有單電源與正負雙電源兩種,其接腳如圖所示,正負雙電源的供電模式可提供負溫度的量測；兩種接法的靜止電流-溫度關(guān)系如圖所示,在靜止溫度中自熱效應(yīng)低(0.08°C),單電源模式在25工下靜止電流約50pA,工作電壓較寬，可在4—20V的供電電壓范圍內(nèi)正常工作非常省電。PlasticPackageSmallOutlineMoldedPackageBOTTOMVIEWTO?92封裝引腳圖“OUT-8N.C.—27NC—36GND—45一*vs—N.C.—N.C.—N.C.SO-8IC式封裝引腳圖MetalCanPackage*BOTTOMVIEWc)IM35DTPlasticPackage*GNDOUTTO-46金屬罐形封裝引腳圖 TO-220塑料封裝引腳圖單電源模式 正負雙電源模式供電電壓35V到-0.2V輸出電壓6V至-1.0V輸出電流10mA指走工作溫度范圍LM35A-55°Cto+150°CLM35C,LM35CA-40°Cto+110°CLM35D0°Cto+100°C封裝形式與型號關(guān)系TO-46金屬罐形封裝引腳圖LM35H丄M35AH丄M35CH丄M35CAH丄M35DHTO-220塑料封裝引腳圖LM35DTTO-92封裝引腳圖LM35C乙LM35CAZLM35DZSO-8IC式封裝引腳圖LM35DMElectricalCharacteristics電氣特性（注1,6）Parameter參數(shù)Conditions條件LM35ALM35CAUnits（Max.）單位Typical典型TestedLimit測試極限（注4）DesignLimit設(shè)計極限（注5）Typical典型TestedLimit測試極限（注4）DesignLimit設(shè)計極限（注5）Accuracy精度（注7）TA=+25°C±0.2±0.5-±0.2±0.5-°CTA=-ior±0.3--±0.3-±1.0￡ta=tmax±0.4±1.0-±0.4±1.0-°CTA=TMIN±0.4±1.0-±0.4-±1.5°CNonlinearity非線性（注8）TMIN<TA<TMAX±0.18-±0.35±0.15-±0.3°CSensorGain傳感器增益（AverageSlope）平均斜率TMIN<TA<TMAX+10.0+9.9,-+10.0-+9.9mV/°C--+10.1---+10.1LoadRegulation負載調(diào)節(jié)（注3）0<IL<lmATA=+25°C±0.4±1.0-±0.4±1.0-mV/mATMIN<TA<TMAX±0.5-±3.0±0.5-±3.0mV/mALineRegulation 線路調(diào)整（注3）TA=+25°C±0.01±0.05±0.01±0.05-mV/V4V<VS<30V±0.02-±0.1±0.02±0.1mV/V
