ADuC: Drive Requirements for ADC

Question asked by NWerner on May 3, 2012
Latest reply on May 14, 2012 by MMA



I want to digitize a differential signal (ENOB<=12; f<2KHz, PGA Gain <8).

However due to various constraints it would be beneficial to AC-couple the signal with a simple CR element.


I wonder whether there are any drive requirements to watch out for? Are there e.g. substantial input capacitance, glitches associated with the muxes or other tripping hazards?


Best Regards
