NOTES:
1. Referenced to VCC = AVCC = VREF = 3.3 to 5.5 V, VSS = AVSS = 0 V at Topr = -20 to 85 ° C / -40 to 85° C unless
otherwise specified.
2. Keep φAD frequency at 10 MHz or less. For M16C/28B, set it 12 MHz or less. Additionally, divide the fAD make φAD
frequency equal to or lower than fAD/2 if VCC is less than 4.2V.
3. When sample & hold function is disabled, keep φAD frequency at 250kHz or more in addition to the limitation in Note 2.
When sample & hold function is enabled, keep φAD frequency at 1MHz or more in addition to the limitation in Note 2.
4. When sample & hold function is enabled, sampling time is 3/ φAD frequency.
When sample & hold function is disabled, sampling time is 2/ φAD frequency.
