ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

(

Typical Operating Circuit, 50Ω system impedance, AVDD = DVDD = PAVDD = +2.1V to +3.6V, f

RF

= 315MHz or 390MHz, T

A

=

-40°C to +125°C, unless otherwise noted. Typical values are at AVDD = DVDD = PAVDD = +2.7V, T

A

= +25°C, unless otherwise

noted. All min and max values are 100% tested at T

A

= +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.

Supply Voltage, AVDD, DVDD, PAVDD to GND (Exposed

Paddle) ...................................………..……………-0.3V to +4V

All Other Pins ………..…Exposed Paddle - 0.3V to (VDD + 0.3V)
Continuous Power Dissipation (T

24-Pin TQFN (derate 20.8mW/°C above +70°C) .....1666.7mW

Operating Temperature……………….………….-40°C to +125°C
Storage Temperature………………….……….…-65°C to +150°C
Lead Temperature (soldering, 10s) ......………………..…+300°C
