01:35 < nmz787> fenn:  ADC is too slow, and the only thing I could find on the DAC is less than 1khz which is much too slow

01:35 < nmz787> these STM boards seem like a good bet
01:39 < nmz787> (3) 12bit ADC at 5MSPS, means I can oversample to gain ENOB, I think... and (4) 12-bit DACs 1 to 15 MHz depending on buffered vs non-buffered... which might lead into the 4 built-in op-amps 
01:40 < nmz787> on top of that, I have experience with this family of chips with respect to the timers and using the ADC with DMA
01:40 < nmz787> muurkha: could have been a bunch of sensors for some piece of equipment
01:43 < nmz787> possibly I just imagined the medical applications, I dont see it mentioned in the datasheet
01:44 < nmz787> I wanted to try EEG with MHz rates... just because I hadn't come across anyone who actually tried it

06:17 < muurkha> I think you will get a lot of noise
07:07 < superkuh> Not sure what cells could have an electrical period that fast. There are some cerebellar ultrafast spiking neurons that do tens of KHz.
07:10 < muurkha> you could maybe be interested in the particular shapes of individual spikes rather than just the Nyquist frequency for the spike rate
07:12 < muurkha> 80 Msps could give you 8000 samples of a single 10-kHz spike.  but, correct me if I'm wrong about this, if you're trying to measure that spike with an electrode gelled onto somebody's skin with carbomer instead of a needle stuck into the cell, those will be 8000 samples of almost pure noise
