Vcc vs Frequency Question - Let's beat this horse one more time
I realize the OP's question pertains to the Atmega32U4 but the new xTinys have info in the data sheet that imply the oscillator functions at full speed over the entire voltage...

Analog mux settling time on Attiny24/44/84
When using the ADC you must consider the input impedance on each channel relative to the S/H capacitance.  For the analog compare I'd guess you'd do the same thing but use...

M328P vs Mega0/1 ADC inputs
Thanks for the detailed reply.  That explains why I never ran across any mention of this issue/phenomenon in the datasheets for the various devices I've used.  I've yet...
