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. φAD frequency must be 12 MHz or less.
3. When sample & hold is disabled, φAD frequency must be 250 kHz or more, in addition to the limitation in Note 2.
When sample & hold is enabled, φAD frequency must be 1MHz or more, in addition to the limitation in Note 2.

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 id
disconnected by the A/D control register.
