Which is most PBP-Friendly external ADC?

[Acetronics2]

16 bits @ 100-200 sps ???

Good luck !!!

It might be overkill, but I like ADS1246.
You can use shiftout/shiftin
EDIT:
This might be more suitable for you

Never used, but it look simple....

Also this maybe a good alternative

It seems like the MCP3426 is only capable of 15sps at 16 bits resolution though.
I'm curious if the 100-200sps is an actual specification or just a number drawn out of the air, perhaps 10sps is enough in reality?

I stumbled upon the AD7680. It's "driven" by the SPI-interface clock and they claim up to 100ksps when clocked by a 2.5MHz SPI clock.
Given the required 200sps the needed SPI-clock speed is way lower so SHIFTIN should certainly be an option. And it's a availble in a 6-pin SOT23 package.

I think there will be so many data to process with a PIC. I do not know what exact processing this will be but I feel it will be very intensive with massive data manipulation...

I want to measure AC voltage without rectification, but as I see, all these ADC have 50/60Hz rejection....

Perhaps the ADS7028?
It's a 12bit converter but it has a built in RMS-module producing a 16 bit true RMS result. But yeah, you going to have to sit down with the datasheet to get it going.
