2.10.3 A/D Conversion Bypass Capacitors

There is a foot pattern on the M30850T2-EPBM board for mounting bypass capacitors for the A/D conversion circuit. Mount

applicable bypass capacitors as occasion demands. Figure 2.21 shows where they are installed.

IMPORTANT

Note on the A/D Converter:

z Because a converter board and other devices are used between the evaluation MCU and the user system, the

A/D converter operates differently from an actual MCU. Make the final evaluation of the A/D converter using
an actual MCU.
