Note:
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at or beyond these ratings in the operational sections of the specifications is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Caution: ESD sensitive device.
Power Amplifier may be damaged if switched on without proper load connected.
