mW (Note 5)
Note 3. All voltages are with respect to GND. GND=0V
Note 4. The exposed pad should be connected to the GND plane.
Note 5. When the temperature is more than 25°C, derating by -18mW is needed. Thermal resistance
θ_JA= 55.4 °C /W (Mounted on the four-layer board that conforms to the JEDEC51)
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
