differences between shunt and series voltage references?



Hi - I need a 4.096 voltage reference for an ADC. I'd like it to be as
accurate as possible, naturally. I've been looking at the various 4.096
voltage references (Maxim alone makes about 45) - and I've noticed that
they for the most part can be grouped as either shunt or as series voltage
references. From what I can tell a shunt V reference is just a zener diode
of the rated voltage. A series V reference is just a voltage regulator. Is
this right? Does one have a major advantage over the other? Thanks for your
help!
