Part Number: LM2903B Hi,
I'have a test circuit for LM2903B.
VCC :3.3V (0.1uF decoupled)
IN- : Voltage reducing from 1.65V to 1.4V (in 15seconds)
IN+: 1.5VDC (Voltage divider from 3.3V)
OUT:2.2kohm pull-up from 3.3V
OUT: Load resistor 39k from…
The LM2903B does not have rail-to-rail inputs; you have to leave a headroom of 2 V to the positive rail.
There are no dual open-collector rail-to-rail comparators in the TSSOP package.
How many comparators do you need? What package sizes can you use…
Part Number: LM2903B Other Parts Discussed in Thread: LM2903 , LM393 Hi team,
My customer has encountered output issue when replacing LM2903 with LM2903B. There is no any other change besides the comparator bom change.
Please see the normal waveforms…
Hello Lee,
As Clemens stated, you can use the LM2903B on split supplies, by applying the -12V to the "GND" pin (pin 4). The valid input range will then be -12V to +10V.
Please beware that the output will now swing "low" to V- (-12V) and not ground…

Hi,
I am using LM2903 Comparator with hysteresis in my circuit. Circuit is as shown below image. I want to know the formula to calculate the Hysteresis (Both High Threshold…
Part Number: LM2903B-Q1 Other Parts Discussed in Thread: LM2903 , LM393LV , LM339 Hello Experts,
We are researching on the LM2903B-Q1. And according to the typical application, there is a pull up resistor on the output to Vlogic. I suppose this is for…
Part Number: LM2903B I am looking for a comparator that has a switching time under 1us and I found the LM2903B which had the following specification which satisfies this.
So, I tried to simulate the LM2903B in PSPICE with similar test conditions but…
Part Number: LM2903B-Q1 Other Parts Discussed in Thread: LM2903 , Hi e2e:
Could you please explain the meaning of response time with its test conditions from the below graph? What does the input overdrive mean? And how to understand the value of both…
Part Number: LM2903B-Q1 Dear Team,
I have a question for wettable flank plating.
Regarding LM2903BWDSGRQ1, dimple point of wettable flank is metal pleated ?
I saw below URL page, it says dimple point is step-cut and then re-plated.
Is it same…
