wat is the function of 47 ohms resistor imean how is it helping in improving the linearity i am talking abt the lm331 figure 3
I suspect that the exact amount of hysteresis is not critical, so long as you keep it well below the minimum input voltage. I think that a few millivolts hysteresis would be adequate. More might cause inaccuracies. I don't have real hardware experience with this part.i have one confusion is to why we want 4.7 mv as the hystersis voltage and what will happen if i increase or decrease i mean an i calculate the value of this resistor then wat parameter should i take into consideration
