General PCB design guidelines

Power supply decoupling should be performed as shown in Figure 50 or Figure 51,

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 50. Power supply and reference decoupling (VREF+ not connected to VDDA)

1. VREF+ input is available on all the packages except LQFP64, whereas the VREF– is available only on

UFBGA176 and UFBGA144. When VREF- is not available, it is internally connected to VSSA.

UFBGA176 and UFBGA144. When VREF- is not available, it is internally connected to VSSA.
