Recommended Land Pattern for AEDR-8400
AEDR-8400 Pad Soldering
In order to provide adequate mechanical strength for the
AEDR-8400 encoder, it is strongly recommended the all
pin-outs need to be soldered including the encoder cen-
ter pad. However, external circuit routing on PCB / FPC
could actually route pin 2, pin 6 and center pad together
hence to have a common ground for the encoder. This
could help to simplify the circuitry routing.
Possible common ground routing:
(Gnd
(Ch A) Pin 4
(V
LED
CC
) Pin 6
) Pin 5
Pin 1 (V
Pin 2 (Gnd)
Pin 3 (Ch B)
LED
)
Likewise, the emitter input voltage supply (Vled) could
share a common voltage supply with detector IC voltage
supply (Vcc) i.e. 2.8V typically. Note that a series resis-
tor is necessary to prevent excess current from flowing
through the emitter. Refer page 6.
