Is there a teensy board that incorporates a 16Bit ADC?
Thanks
Low bandwidth reading a DC signal typically 4-20ma converted via a shunt and a opamp circuit to whatever input is required by the ADC. I was hoping there was a higher ADC input option on a teensy, more than 12 bits, maybe 16 or an over sampling option?
Mark, thanks for your insight on this subject. I have been developing with 16 bit ADCs with other microcontrollers and mitigated noise using various methods with much success. But back to the orginal question, are there any teensy variants with 16 bit (or greater than 12) inputs? (BTW, I don't have to use all 16 bits, one method I use is by shifting off the noisy bits)
Unless you happen to synchronize perfectly, 1Hz noise doesn't average out if you average over anything close to 1 second.
if you average 256 times, you gain 4 bits. 16 bits dynamic range from a 12bit ADC really is no problem at all at low sample rates.

Only if the noise is high freq, white noise - and it often isn't either one. Go ahead, try it.
