Friends, as can be seen from the circuit drawing, it is a sample hold circuit. The 30mV signal is generated by a low impedance sensor.
x100 standard opamp amplifier.
Since I have not yet designed the complete system, I cannot add the schematic to the forum.
My current problem is whether the sample and hold circuit that I will make with the analog switch should be at the input or at the output.Under normal conditions, I connect the sample hold circuit to the output of the x100 amplifier. But I have never connected it to an input until today and I am wondering if this will cause a problem.
