LAYOUT AND POWER SUPPLY BYPASSING
It is a good practice to design a layout with compact, minimum
lead lengths. The leads to the input 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 0.01 μF to 0.1 μF disc or
chip ceramic capacitors. Low ESR 1 μF to 10 μF tantalum or
electrolytic capacitors should also be applied at the supplies to
minimize any transient disturbance and filter low frequency
ripple (see Figure 54). Notice that the digital ground should also
be joined remotely to the analog ground at one point to
minimize digital ground bounce.
