9 Power Supply Recommendations

The devices are designed to operate from an input voltage supply range between 1.5 V and 18 V (4.5 V to 25 V biased). This input supply must be well regulated. Proper bypassing of input supplies and internal regulators is also critical for noise performance, as is PCB layout and grounding scheme. See the recommendations in the Layout section.
