If all the harware suggestions are followed the cost of the ADC system is very significantly increased.</p><p>In my experience with on chip 12 bit ADCs there is no advantage at all in using seperate supplies for the ADC or ADC ref, RC filtering worked just as well. (A 16 bit design might well be more sensitive than a 12 bit design.) In other applications (high end audio at 24 bit) no noise advantage resulted form separating digital and analogue ground planes.</p><p>&nbsp;</p><p>Have you any data that compares the performance from a cost optimised application with that from a performance optimised design ?</p><p>&nbsp;</p><p>MK</p><img src="https://community.element14.com/aggbug?PostID=17476&AppID=73&AppType=Weblog&ContentType=0" width="1" height="1">
