1. Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Functional operation at conditions other than the operating conditions
specified is not implied. Only one Absolute Maximum Rating should be applied at any one time.
2. Mounted on an FR4 board with exposed paddle connected to single layer PCB plane.
3. Derate 20mW/°C above 25°C ambient temperature for TDFN34-16 package. Increased power dissipation is possible with additional PCB heatsinking.
