MCP3204 sample rate confusion

[kangyou]

Hi everybody.

Recently I'm working with MCP3204. It is declared to have 100ksamples/s speed at 5V with 12 bit resolution. So will I truly get 100k 12 bit samples per second(for the ideal case)? Or I will get 100k/12bit=8.3k samples per instead?

This is a noob question but it'll be very appreciated if anyone could give me an answer.

And Happy New Year for everyone!

You will get (up to) 100k 12 bit samples per second, BUT that depends on getting the SPI clock rate high enough.

I seem to recall that joan has gotten ~60k samples per second.

Thank you. That's great to know the "sample" mentioned here is the 12-bits one. Last night I tried to use library from http://www.airspayce.com/mikem/bcm2835/ and that worked. I can tolerate the sampling jitter somehow.
