Comments / Signal routing
Close (<5mm) to VSUP1, VSUP2 terminals with good ground return
Close (<3mm) to digital supply terminals (EVDD, EVSS) with good
ground return.
The positive analog (VREFH, VDDA) and the digital (EVDD) supply
should be connected right at the C3.
Bulk Capacitor
Close (<5mm) to LIN terminal.
Total Capacitance on LIN has to be below 220pF.
