Printed Circuit Board Layout
Care in PCB layout is essential for proper
function. The components connecting to
the RSN input should be placed in close
proximity to that pin, such that no
interference is injected into the RSN pin.
Ground plane surrounding the RSN pin is
advisable.
Analog ground (AGND) should be
connected to battery ground (BGND) on
the PCB in one point.The capacitors for the
battery should be connected with short
wide leads of the same length.
