NOTES: 1. The leakage current is defined in the leakage current table with Px.x/Ax parameter.
2. The analog input voltage range must be within the selected reference voltage range V
R+
to V
R--
for valid conversion results.
3. The internal reference supply current is not included in current consumption parameter I
ADC10
.
4. The internal reference current is supplied via terminal V
CC
. Consumption is independent of the ADC10ON control bit, unless a
conversion is active. The REFON bit enables the built-in reference to settle before starting an A/D conversion.
