Bandgap Analog Voltage Filter Circuit

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.
