I have a voltage reference in the circuit and I thought I can feed that reference to AREF pin of ATMEGA as well:
The current at "1.024V" tag is around 200 uA, any current drawn by the AREF can affect the reference voltage to some degree.
Does the AREF pin draw any current? how much?
Can any noise on the AREF pin (or the MCU itself) affect the reference voltage?
Can I dump that 10 uH inductor (LC filter) which is recommended and used in most designs at AREF pin?
