Bandgap Analog Voltage Filter Circuit

Note: Ground VSSBGPE at capacitor
Note: .
•
Place C as close as possible to package pin.
•
R must be placed between the 2.5V supply and L.
•
Route VCCBGPE and VSSBGPE as differential traces.
•
VCCBGPE and VSSBGPE traces must be ground referenced (No 2.5V references).
•
VSSBGPE should be grounded at the capacitor.
•
Max total board trace length = 1.2".
•
Min trace space to other nets = 30 mils.
