LAYOUT AND POWER SUPPLY BYPASSING
It is good practice to employ a compact, minimum lead length
layout design. 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 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 capaci-
tors should also be applied at VDD to minimize any transient
disturbance and filter any low frequency ripple (see Figure 26).
Users should not apply switching regulators for VDD due to the
power supply rejection ratio (PSRR) degradation over frequency.

digital and analog ground references. To minimize the digital
ground bounce, the DGND terminal should be joined remotely
at a single point to the analog ground plane (see Figure 26).
