Hello Joselito,
The actual circuits are proprietary information. But suffice to say, measuring comparator offset is pretty basic.
The input is ramped up from below the reference voltage, to above the reference voltage (say ±20mV). For the LM2903 family…
Part Number: LM139A Other Parts Discussed in Thread: LM139-N Hi Experts
Can someone provide the test configuration used for Figures 4 & 5 in the data sheet?
I’d like to know the input wave forms for both inputs.
Thanks!

Part Number: LM139A Other Parts Discussed in Thread: LM139-N , , Hi,
Good Day.
What is the difference between LM139J/883 and LM139AJ/883? Is this related to the die used? Or the transition of National Semiconductor devices to Texas Instruments?
Please…
Part Number: LM139A Other Parts Discussed in Thread: LM339 , LM139 With a negative input of -12V through 3K Ohms, we've never experienced a false state but are we "on the edge"? Opposite input = +1.2V through 750 Ohms.. Operation at +15 to…
Part Number: LM139A Other Parts Discussed in Thread: LM339 Hello. I have some questions regarding the datasheet/specifications for the LM139A comparator. They seem similar to other questions that have been asked, so please bear with me, as I'd like to…
Part Number: LM139A How does one calculate the power dissipation for this part? What is the rated power dissipation for this part?
