A/D Accuracy Measure Circuit

Notes:

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 5.3 “A/D Accuracy Measure Circuit”.

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 to 85°C/-40 to 85°C unless

otherwise specified.
