5.4 Recommended Operating Conditions

Over operating free-air temperature range and supply voltages (unless otherwise noted). The functional performance of the

device specified in this data sheet is achieved when operating the device within the limits defined by the Recommended

Operating Conditions. No level of performance is implied when operating the device above or below the Recommended

Operating Conditions limits.
