I've seen ADC with on-chip voltage reference. Does an ADC usually have an on-chip reference?
The problem is that I am designing an ADC and I need two voltage references (Ref and Ref/16). For writing a paper, I can leave it alone. But for real design, should I worry about the Ref/16 reference? like if ref = 1v, there is no way I can get a accurate 62.5mV (error within 1%) in a real application. If I do need a Ref/16 and Ref, it is better I design it on-chip by myself, right?
