10 Power Supply Recommendations

This device is designed to operate from an input voltage supply between 1.5 V and 16 V. Ensure the supply is well regulated. Proper bypassing of input supplies and internal regulators is also critical for noise performance, as is the quality of the PCB layout and grounding scheme. See the recommendations in the Layout section.
