1. The value is obtained when φAD frequency is at 16 MHz. Keep φAD frequency at 16 MHz or lower.
2. With using the sample and hold function
1. Measured when one D/A converter is used, and the DAi register (i = 0, 1) of the unused D/A converter is set to
00h. The current flown into the resistor ladder in the A/D converter is excluded. IVREF flows even if the VCUT
bit in the AD0CON1 register is set to 0 (VREF not connected)
