5. Electrical Characteristics

Notes:

This applies when using one A/D converter, with the ADSTBY bit for the unused A/D converter set to 0 (A/D

operation stopped (standby).

Use when AVCC = VCC1 = VCC2.

Do not use A/D converter when VCC1 > VCC2.

When analog input voltage is over reference voltage, the result of A/D conversion is 3FFh.

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 5.2 “A/D Accuracy Measure Circuit”.

5.1.4

D/A Conversion Characteristics

Notes:

This applies when using one D/A converter, with the D/A register for the unused D/A converter set to 00h.

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)).

AVCC = VCC1 = VCC2 = VREF = 3.0 to 5.5 V, VSS = AVSS = 0 V at Topr = -20°C to 85°C/-40°C to 85°C unless otherwise

specified.
