Taw qhia

LM35 series yog qhov sib xyaw ua ke ntsuas hluav taws xob ntsuas hluav taws xob nrog cov hluav taws xob tso tawm tawm ncaj qha rau qhov ntsuas kub. LM35 yog peb lub davhlau ya nyob twg ntsuas kub ntsuas los ntawm National semiconductors. Nws tuaj yeem ntsuas kub ntawm -55 degree Celsius mus rau +150 degree Celsius. Qhov hluav taws xob tso tawm ntawm LM35 nce 10mV ib qib Celsius nce hauv qhov kub thiab txias. LM35 tuaj yeem ua haujlwm los ntawm 5V cov khoom siv thiab sawv ntawm tam sim no tsawg dua 60uA. Tus pin tawm ntawm LM35 tau qhia hauv daim duab hauv qab no.

Nta

• Ntsuas ncaj qha hauv Celsius (Centigrade)

• Tawm + 10-mV/° C Scale Factor

• 0.5 ° C Ua kom raug qhov tseeb (ntawm 25 ° C)

• Rated rau Full -55 ° C txog 150 ° C Range

• Haum rau Cov Ntawv Thov Hauv Chaw Nyob

• Tus Nqi Them Nqi Vim Wafer-Trimming

• Ua haujlwm los ntawm 4 V txog 30 V

• Tsawg dua 60-μA Kev Tso Dej Tam Sim No

• Tsawg Tus Kheej Cua Kub, 0.08 ° C hauv Tseem Cua

• Tsis-Linearity Tsuas yog ± ¼ ° C Raug

• Tsawg-Impedance Output, 0.1 Ω rau 1-mA Load PinOuts Ntawm LM35 tau qhia hauv duab.
