Part Number: LM34 Other Parts Discussed in Thread: LMV331 Hi,
In one of our Ethernet board design, we are used temperature sensor LM34DM. LM34 is interfaced to comparator LMV331.
We have set the LM34DM to 153 F Turn On Temperature to shut down the board…

Hi David,
We are captured the voltage across R133 when board gets shut-off.
Before board get shut-off, the voltage across R133 = 0.920V
Please find the capture of oscilloscope when trigger level set to…
Part Number: LM34 Hi,
I am looking into a temperature sensor for a future project. I see that the LM34 states that it has a maximum supply voltage of -0.2V. Is this correct?
Thanks
Part Number: LM34 I am connecting LM34CZ/NOPB to a PLC analog input 0-10 V. LM34 is powered by 24 VDC and I get .560V at about 78 degrees Fahrenheit on the output signal of LM34 but how do I interpret that signal? My PLC Engineering units is set to receive…
Part Number: LM34 I have a 4-20mA sensor and LM34AH sensor. The 4-20mA sensor works correctly when 24VDC source is applied. Also the LM34AH works correctly when DC source is applied. The issue is when both of these units are hooked up using the same power…
Part Number: LM34 Other Parts Discussed in Thread: LMT84 , TMP235 LM34's output stage can only source 16uA and sink 1uA. This is from Page 11 of the L M34 datasheet :
Why can the Class-A output amp only source 16uA if it has an output impedance of 0…
Part Number: LM34 Other Parts Discussed in Thread: LMT87 , LM94022 Hello all:
Searching around on the internet (including TI forums), I can't seem to find a definitive answer to my question:
I'm using an LM34DM (SO-8) in "minimal" configuration: connections…
Other Parts Discussed in Thread: LM34 , LMT87 On the LM34 datasheet page 14 Figure 17 it shows how to use two diodes to get to a negative temperature. I am confused as how to present this to a microcontroller's Vref- and Vref+ inputs for the AtoD. Would…
Other Parts Discussed in Thread: LM34 When reading a lm34 from a microchip PIC16F1825 10 bit atod the readings were flaky - all over the place. I will ask microchip about this but does the analog output of the lm34 require a 0.1uf capacitor to keep the…
