NOTES:
1. Referenced to VCC1=AVCC=VREF=3.3 to 5.5V, VSS=AVSS=0V at Topr = −20 to 85°C / −40 to 85°C unless otherwise specified.
2. If VCC1 > VCC2, do not use AN0_0 to AN0_7 and AN2_0 to AN2_7 as analog input pins.
3. φAD frequency must be 12 MHz or less. And divide the fAD if VCC1 is less than 4.0V, and φAD frequency into 10 MHz or less.
4. When sample & hold is disabled, φAD frequency must be 250 kHz or more, in addition to the limitation in Note 3.
When sample & hold is enabled, φAD frequency must be 1MHz or more, in addition to the limitation in Note 3.
