General PCB design guidelines

Power supply decoupling should be performed as shown in Figure 41 or Figure 42,

depending on whether VREF+ is connected to VDDA or not. The 100 nF capacitors should be

ceramic (good quality). They should be placed them as close as possible to the chip.

Figure 41. Power supply and reference decoupling (VREF+ not connected to VDDA)

1. VREF+ input is available on all package whereas the VREF– s available only on UFBGA176+25 and

TFBGA240+25. When VREF- is not available, it is internally connected to VDDA and VSSA.

1. VREF+ input is available on all package whereas the VREF– s available only on UFBGA176+25 and

TFBGA240+25. When VREF- is not available, it is internally connected to VDDA and VSSA.
