General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 31 or Figure 32,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.
Figure 31.
Power supply and reference decoupling (VREF+ not connected to VDDA)
1. VREF+ and VREF– inputs are available only on 100-pin packages.
