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…
Other Parts Discussed in Thread: LM34 I am trying to make a temperature probe using the LM34 temp sensor. Is there any maximum distance I can run wire leads?
Other Parts Discussed in Thread: LM34 TI group,
I have a school project where we are building a thermometer in NI multisim. We are supposed to use the LM34 temp sensor. I am adding a custom component in MS. The function block diagram is everything that…
Part Number: LM35 Other Parts Discussed in Thread: LM34 , I have a LM35 reading 0.644 volts in a room of 70 F. It would possibly be true if it was a LM34. It does not really change values if I hold it in my fingers. Can the device be damaged by a static…
Cheem, You will need a temperature controlled oil bath with an RTD reference probe. Place about 10 LM34 devices on a pcb board and test them in the oil bath. Sweep the temperature over the range of interest. Make sure to have enough soaking time at…
Other Parts Discussed in Thread: LM34 I want to know if the temperature sensor LM34 is capable if cemented onto a metal surface and still remaining accurate to measure surface temperature.
