Note 1. All voltage is respect to ground.
Note 2. In case that PCB(size: 76×114mm,1.6mm, 4 layer) , material is FR4, base on JDEC51-7, and temperature is
25℃, windless.
Note: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
