Hello friends, I found a signal conditioning circuit for a power transformer to be applied to the analog input of a microcontroller.
the output transformer is an AC voltage with an amplitude in millivolts, but does not understand the circuit to convert that signal into a DC voltage proportional to load current. And there's a part where mixed-voltage AC voltage DC, search the Internet and the circuit is an attenuator.
In the circuit using an operational amplifier LMC6484AIM and datasheet appears in an application where the same situation happens, please attach a picture of the datasheet.
Please help with technical information and documents to help me understand this application of operational amplifiers
