PRODUCTION DATA.
These devices operate from an input voltage supply between 4.5 V and 18 V. These devices are not designed for split-rail operation. The VIN and VDD pins must be the same voltage for accurate high-side short circuit protection. 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.
