Electrical characteristics

General PCB design guidelines

Power supply decoupling should be performed as shown in Figure 51 or Figure 52,

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.

1. VREF+ and VREF– inputs are both available on UFBGA176 package. VREF+ is also available on all packages

except for LQFP64. When VREF+ and VREF– are not available, they are internally connected to VDDA and

VSSA.
