Appendix B : PCB Layout
Suggestion
The following shows an example
of a PCB layout that would result
in good electrical and EMI perfor-
mance. Things to note:
1. The ground plane should be
continuous under the part, but
should not extend under the
shield trace.
2. The shield trace is a wide, low
inductance trace back to the
system ground.
3. The AGND pin should be con-
nected to the ground plane and
not to the shield tab.
4. C1 and C2 are optional supply
filter capacitors; they may be
left out if a clean power supply
is used.
5. V
LED
can be connected to
either unfiltered or unregu-
lated power supply. If V
LED
and V
CC
share the same power
supply and C1 is used, the
connection should be before
the current limiting resistor
R2. In a noisy environment,
supply rejection can be en-
hanced by including C2 as
well.
The layout corresponds to the
following application circuit
diagram.
R2 is the current limiting resistor,
while R1 is a weak pull down
resistor for the input of the
switching transistor. Do not float
the input of the switching
MOSFET. The DIP switch is used
to select between driving the
875 nm or 940 nm LED.
