No as written before it is hard to read to me. I am used to other (correct) self-explaining standardized symbols for opamps, relays and connectors. This translates reality to paper (and paper to reality) so to speak.
RCR is OK as already oversampled 4 times, also with slightly lower R values.

I didn't understand. Are you saying me to redraw the circuit diagram?
Does that mean the circuit is malfunctioning? I'm ready to redraw for your advice.

No I am not saying that. It seems we have trouble communicating in international english.
Technical education does/did not teach relays, opamps, connectors to be all drawn as identical squares. So if one is not used to such everything looks the same. Which they are in fact in the drawing, all squares/rectangles. This gives trouble as it is not clear what part A (a square) is or what part B is (also a square).
The different parts usually have typical shapes to avoid misinterpretation or even faults.

I understood the circuit diagram to mean it's hard to read. Of course there might be a standard specification, but I use an eda library like samacsys to produce pcb quickly and accurately. Thanks for everyone's advice.

Libraries like samacsys are supposed to be convenient but they are not 100% accurate. I have come across wrong footprints a number of times. And (of course) I have found out the hard way, after PCBs were fabricated.
Also, I agree with what jean-paul is saying. It is not ok to draw up an op-amp as a square box with wires. That is in fact bothering me even more that the inaccurate footprints in these libraries.

@Dimdim Thanks for letting me know in advance. What program do you use? I use orcad. I also review all footprints and the size of padstacks that make it up and then I use them. I'm contributing to the wrong footprint of samacsys too but they are only quick to respond to mail and the actual library is not fixed. So I gave up helping.
IMHO OrCad Capture is the best schematic drawing program I have known since the late 80's.

I still use Eagle, a pretty ancient version of it. I am thinking of switching to Kicad but I keep putting it off because of the learning curve, especially for importing the dozens (if not hundreds) of Eagle designs that I have made over the years.
