Which is most PBP-Friendly external ADC?

[CuriousOne]

Hello.

I need a simple, 1 channel input, external ADC, which can do 16 or more bits. I don't need fast speeds, I need only 100-200 samples per second sampling speed. I've searched digikey, but there are so many....

So I'm asking, maybe someone has any practical experience using external ADC with PBP ?

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...
