Stresses beyond those listed under âAbsolute Maximum Ratingsâ may cause permanent damage to the device. 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.
DC ELECTRICAL CHARACTERISTICS
(Typical Application Circuit, 50⦠system impedance, PAVDD = AVDD = DVDD = HVIN = +2.1V to +3.6V, fRF = 308MHz, 315MHz, or
433.92MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at PAVDD = AVDD = DVDD = HVIN = +2.7V, TA = +25°C,
unless otherwise noted.) (Note 1)
