I have been experimenting with a fast logger using an Adafruit Data Logging Shield and a sketch to log 8-bit data from an Arduino analog pin. Any SD shield/module could be used. I have been able to log data to an SD card at 100,000 samples per second. If there is any interest in this sketch I will…

Logging 100 ksps with the Arduino internal ADC

ENOB (not ENOD) has a very precise meaning.

I included two papers with the fast logging sketch that describe how it is determined for the AVR ADC.
