NOTES:
1. Referenced to VCC1=AVCC=VREF=4.0 to 5.5V, VSS=AVSS=0V at Topr = -40 to 85
°C / -40 to 125 °C unless otherwise
specified. T version = -40 to 85
°C, V version = -40 to 125 °C.
2. AD frequency must be 12 MHz or less.
3. When sample & hold function is disabled, AD frequency must be 250 kHz or more, in addition to the limitation in Note 2.
When sample & hold function is enabled, AD frequency must be 1MHz or more, in addition to the limitation in Note 2.

NOTES :
1. Referenced to VCC1=VREF=4.0 to 5.5V, VSS=AVSS=0V at Topr = -40 to 85
°C / -40 to 125 °C unless otherwise specified.
T version=-40 to 85
°C, V version=-40 to 125 °C
2. This applies when using one D/A converter, with the D/A register for the unused D/A converter set to “00h”. The
resistor ladder of the A/D converter is not included. Also, when D/A register contents are not “00h,” the IVREF will
flow even if Vref is disconnected by the A/D control register.
