General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 43 or Figure 44,
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 43. Power supply and reference decoupling (VREF+ not connected to VDDA)
1. VREF+ input is available on all the packages except TFBGA100 whereas the VREF– is available only on
UFBGA176 and TFBGA216. When VREF- is not available, it is internally connected to VDDA and VSSA.
Figure 44. Power supply and reference decoupling (VREF+ connected to VDDA)
1. VREF+ input is available on all the packages except TFBGA100, whereas the VREF– is available only on
UFBGA176 and TFBGA216. When VREF- is not available, it is internally connected to VDDA and VSSA.
