and also in the second OPAMP we connect the 2 diodes after 47k? so why this
and in fig 2 we connect 200k parallel with .01uf ,so is this low pass filter and how can I chose the value of 200k and .01uf
this is control board for power supplyIt would be helpful if you would provide more information about what you are building? it's not at all clear from the schematic.
can you explain more pleaseIf the inverting and non-inverting inputs of the opamp have similar resistance paths for DC bias current the effect of DC offset drift will be reduced.
Can you read more?can you explain more please
Thanks so much ,you are rightCan you read more?
You've been told that it is to minimize the effect of DC offset drift related to the DC bias currents. So go look into the effects of DC bias currents in opamps.
