Board Layout and Bypassing
To obtain the best performance, a printed circuit board with
a solid ground plane is required. Layout for the printed
board should ensure digital and analog signal lines are
separated as much as possible. Care should be taken not
to run any digital signals alongside an analog signal. All
analog inputs should be shielded by GND. V
REF
, REFCOMP
and V
DD
should be bypassed to the ground plane as close
to the pin as possible. Maintaining a low impedance path
for the common return of these bypass capacitors is
essential to the low noise operation of the ADC. These
traces should be as wide as possible. See Figures 16a-e
for a suggested layout.
