Use of dedicated analog and digital ground planes on the PCB is recommended for
high-speed circuit applications to provide low parasitic inductance and resistance.
Ground planes under the digital pins and layers should be avoided to minimize parasitic
capacitances.
The separation of the analog signal from the digital output is mandatory to prevent
noise from coupling onto the input signal.
Power supply bypass capacitors must be placed as close as possible to the IC pins to
improve high-frequency bypassing and reduce harmonic distortion.
All leads must be as short as possible, especially for the analog input, so as to
decrease parasitic capacitance and inductance.
To minimize the transition current when the output changes, the capacitive load at the
digital outputs must be reduced as much as possible by using the shortest-possible
routing tracks.
Choose the smallest-possible component sizes (SMD).
