Precautions concerning wiring
qA bare ground should be used for GND.
wThe wiring pattern of the I2C BUS should be separate from that of the
analog unit, to avoid crosstalk.
eParallel positioning of the SCL and SDA lines of the I2C BUS should be
avoided wherever possible. If they are adjacent, they should be shielded.
