Table 5.8
A/D Conversion Characteristics
(VCC1 = VCC2 = AVCC = VREF = 4.2 to 5.5 V, VSS = AVSS = 0 V, Topr = -20 to 85
°C,
f(CPU) = 32MHz unless otherwise specified)
NOTES:
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
Table 5.9
D/A Conversion Characteristics
(VCC1 = VCC2 = VREF = 4.2 to 5.5 V, VSS = AVSS = 0 V, Topr = -20 to 85
°C,
f(CPU) = 32MHz unless otherwise specified)
NOTE:
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)
