Electrical characteristics

General PCB design guidelines

Power supply decoupling should be performed as shown in Figure 52 or Figure 53,

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.
