General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 90 or Figure 91,
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 90. 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.
Figure 91. Power supply and reference decoupling (VREF+ 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.
