This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. The digital control inputs are zener protected; however, permanent damage may occur on unconnected units under high energy electrostatic fields. Keep unused units in conductive foam at all times. Do not apply voltages higher than VDD or less than GND potential on any terminal except VREF and RFEEDBACK. 1. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
