Figure 38 illustrates a typical circuit connection for a simple application. The circuit illustrated is for information

only. The whole board design should be considered to meet the USB specification as a USB compliant product.

NOTE: C1, C2: 10 µF

C3, C4, C7, C8: 1 µF (These capacitors must be less than 2 µF.)

C5, C6: 10 pF to 33 pF (depending on crystal resonator)

C9, C10, C11, C12: The capacitance may vary depending on design.

In this case, the analog performance of the A/D converter may be degraded.
