#171834 - it is possible? Responding to: ???'s previous message |
I did not read whole Aduc's datasheet - but - is it possible to bypass all low-pass filters, featured by this ADC?
If not - note "Normal mode rejection" of 50/60 Hz signal. in this case i think You must change ADC to something with 1000-2000 Hz samplerate , at least. Or use some peak detector circuit on ADC's front. regards |
