Gain errror of ADC (Read 2489 times)

babunp114525 New Member Offline Posts: 5	Gain errror of ADC Apr 19^th, 2007, 7:35am The gain error of any ADC is measured at the last code transition point i.e. at the full scale range. Is it beacuse, we are measuring the worst case scenario as the input is FS? or what is the reason behind this? Thanks, Babun

Its like taking 2 intersecting pencils, assuming one is ideal and measuring the deviation at the far end considering the intersecting point as origin. Hope that helps. NitinAtCadence
