LAYOUT AND POWER SUPPLY BYPASSING
It is a good practice to employ compact, minimum lead length
layout design. The leads to the inputs should be as direct as
possible with a minimum conductor length. Ground paths
should have low resistance and low inductance.
Similarly, it is also a good practice to bypass the power supplies
with quality capacitors for optimum stability. Supply leads to the
device should be bypassed with disc or chip ceramic capacitors
of 0.01 μF to 0.1 μF. Low ESR 1 μF to 10 μF tantalum or
electrolytic capacitors should also be applied at the supplies to
minimize any transient disturbance and low frequency ripple
(see Figure 42). Note that the digital ground should also be
joined remotely to the analog ground at one point to minimize
the ground bounce.
