Thus, due to the datasheet, the pinout is this:
I doubt that there would be any problem in the circuit that I wired up.
In this circuit from right to left you can see the 24v Dc switching power supply and then buck module to make around 5v Dc to supply circuit(everything save soldering iron). and also for MCU and Op-Amp I'm using two LDO (one for MCU and another for Op-Amp). everything in this circuit is working very well save Op-Amp. the 24v Dc switching power supply has two +V and two -V and one earth (and one L and one N for 220AC as input). now look at this image:
I connect the 'COM' probe of my DMM to number 1 (as GND). when I connect the red probe on my DMM to this point, it shows me 0v. when I connect it to the number 2 point, it shows me 0v again. when I connect it to num' 3, it shows me 40mv. for num' 4 and 5, it shows me -20mv.
I didn't state it. it was quoted from a guy in this link that his forum name is 'sparkybg'. :Half cycle = half period, as you stated :-

I don't use the 24V AC. mine is 24v DC. my project is based on this project as I said already:Can you post the schematic of that part of your circuit?

My Op-Amp is MCP6V07T-E/SN. you can see its datasheet here:Are you sure you have the + and - inputs the right way round?

Ok, let me show you an image of the circuit:With respect to what are you measuring GND? Normally GND is the reference point.
