ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(
Typical Application Circuit, 50
system impedance, tuned for 315MHz to 433.92MHz operation, VAVDD = VDVDD = VPAVDD = +2.1V
to +3.6V, fRF = 300MHz to 450MHz, fCRYSTAL = 16MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VAVDD
= VDVDD = VPAVDD = +2.7V, TA = +25°C, unless otherwise noted. All min and max values are 100% tested at TA = +125°C, and
guaranteed by design and characterization over temperature, unless otherwise noted.)
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 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.
