1. The value when φAD frequency is at 10 MHz. Keep φAD frequency at 10 MHz or lower.
2. Sample and hold function is not available.
1. Measurement when one D/A converter is used, and the DAi register (i = 0, 1) of the unused D/A converter is set
If f(CPU) (=fAD) is 24 MHz, divide f(CPU) by 3 to make it 8 MHz. The conversion time in this case is 6.1 μs.
to 00h. The current flown into the resistor ladder in the A/D converter is excluded. IVREF flows even if VCUT
bit in the AD0CON1 register is set to 0 (VREF not connected)
