Note 1: Referenced to VCC=AVCC=VREF=3.3 to 5.5V, VSS=AVSS=0V at Topr = -20 to 85 °C / -40 to 85 °C unless otherwise
specified.
Note 2: AD operation clock frequency (ØAD frequency) must be 10 MHz or less. And divide the fAD if VCC is less than 4.2V,
and make ØAD frequency equal to or lower than fAD/2.
Note 3: A case without sample & hold function turn ØAD frequency into 250 kHz or more in addition to a limit of Note 2.
A case with sample & hold function turn ØAD frequency into 1MHz or more in addition to a limit of Note 2.
