Overview
6-1 Overview
The MN101C117 has an internal A/D converter with 10-bit resolution. A
sample-and-hold circuit is contained on-chip and software can switch the
analog input between channels 0 to 7 (AN0 to AN7).
When the A/D converter is stopped, power consumption can be reduced by
turning off the internal ladder resistors.
