“Today we have the ADS830 (8bit, 80MSPS) analog to digital converter from Texas Instruments. This is a pipelined ADC so it is likely that each of the vertical sections in the center (there are six) probably contains a two-bit flash ADC, DAC and appropriate amplifiers for taking the difference and gain after each stage. It is likely that there is a single voltage reference location that supplies all of the comparators. Given that this is an 8bit ADC that incorporates some sort of digital error correction, and there are six 2bit stages, there may be some stage redundancy to allow for higher certainty of the lower bits.”
