These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
MAX1472 ELECTRICAL CHARACTERISTICS
(Typical Application Circuit, output power is referenced to 50Ω, VDD = 2.1V to 3.6V, VENABLE = VDD, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VDD = 2.7V, TA = +25°C, unless otherwise noted.) (Note 1)
