Hi KlausST hope you and everybody here having good weekend!
*Yes I will be using this circuit, based on the results i am getting on real hardware. Will keep posted.
*Can you suggest any other amplifier? which can work on single supply? With better specs?
*No, I cant use dual supply.
I really appreciate help provided by dear forum members and happy to part of you guys! Cheersss....
However, I have 2 doubts:
1. I will be using this circuit now on breadboard; I think i dont have to use that 4K resistor from the legs of 50E. Those were only to simulate the differential voltage obtained from sensor. In real hardware, sensor itself provide that impedance (4k...6k). Correct me if I am wrong. I am posting here schematic:
As we discussed it is good to start with resistor 10X greater that the impedance provided by sensor. So in that case combination of 47k, 470k or 68k & 680k or 100k & 1M will also provide gain of 10. BUT....BUT what these different values will have effect on output? or they will not affect it? What points i must consider while choosing these value? It should be larger or smaller.....what criteria?
2. And you asked to put the cap of 470pF across resistors to reduce noise problems. As per my understanding you must calculated that using formula; fc=1/(2*pi*R*C). But how can I determine my fc here? Would be helpful if you can make it more simpler if possible.
Thanks.
