5. Electrical Characteristics
Figure 5.3
A/D Accuracy Measure Circuit
Notes:
1.
Use when AVCC = VCC1 = VCC2.
2.
Do not use A/D converter when VCC1 > VCC2.
3.
When analog input voltage is over reference voltage, the result of A/D conversion is 3FFh.
4.
Flash memory rewrite disabled. Except for the analog input pin, set the pins to be measured as input ports and
connect them to VSS. See Figure 5.3 “A/D Accuracy Measure Circuit”.
5.1.4
D/A Conversion Characteristics
Notes:
1.
This applies when using one D/A converter, with the D/A register for the unused D/A converter set to 00h.
2.
The current consumption of the A/D converter is not included. Also, the IVREF of the D/A converter will flow even
if the ADSTBY bit in the ADCON1 register is 0 (A/D operation stopped (standby)).
Table 5.7
A/D Conversion Characteristics (2/2) (1)
AVCC = VCC1 = VCC2 = VREF = 1.8 to 5.5 V, VSS = AVSS = 0 V at Topr = -20°C to 85°C/-40°C to 85°C unless otherwise
specified.
