Chapter 6 A/D Conversion Functions

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.
