Part Number: LM397 Other Parts Discussed in Thread: TL331 , LM339 Hello team,
Customer had several issues on LM397 device (DC1649) during In Situ Test. Indeed, they noticed a shift on the Output_Low which exceeds the 400mV limit (with a pull up 5V, 500Ohms…
Part Number: LM397 Other Parts Discussed in Thread: LM339 Hello team,
My customer uses our LM397, there is 29V of BAT_F, but sometimes the VS voltage change from 12V to 0, the voltage of pin4 is higher than pin5, it is risk? our part will be broken? t…
Other Parts Discussed in Thread: TL331 , LM397 , LM339 , LM393 , LM393-N looks like the spec sheet does not have this important information, It's open drain and I would expect it to be higher then Vs. Can someone confirm what it is ?
Do you have a recommended comparator I should use? IE LM397 (single general purpose voltage comparator)?
For the low pass circuit, I would hook the resistor-capacitor up in series I assume to slow the digital signal down for my Vref value?
Thanks for…
Hello Nibin,
The LM2903AV is the dual version, and the TL331 or LM397 is the single version.
The LM2903AVQPWR is the dual version.
The single is the TL331 or LM397, though the offset specs are a little worse.
Part Number: LM339A Other Parts Discussed in Thread: LM339-N , TL331 , LM397 , LM393 Hello,
I has to use two of four comparators of a LM339AM in a safety function.
How are the internal circuits an components connectet and there are more components as in the…
Other Parts Discussed in Thread: LM397 Hello,
I am using an op-amp comparator circuit in my design.
How do I know the maximum operating frequency of an op-amp.
thank you.
Hello Kiran,
TI makes many different versions and grades of the LM139, which have come from different sources. Can you tell us the exact part number you are interesed in.
Also, what is the part number of interest for the LM397.
Other Parts Discussed in Thread: LP211 , TL331 , LM397 , LM393 , LM339 Hi,
I want to do a zero detection on the main voltage (in France, 230Vac and 50Hz). Before doing it in real, I try to do it with simulation.
This is my design:
VF2 is ok, but VF3 is not…
Hello Maxime,
This same question was posted yesterday by Kiran Kerai.
My response was that we have many different grades and versions of the LM139. For a question like this, I need to know the exact part number the customer wants to answer this question…
