Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. On the pins RFVDD (3), PTATBIAS (6), DVDD (9), CPOUT (20), VARIN (21) and AVDD (23), the maximum input voltage should not
exceed 2.75V.
4. Devices are ESD sensitive. Handling precautions recommended. Pin 4, RFOUT, has less ESD protection (Human body model (HBM) of
200V and Charged Device Model (CDM) of 500V).
5. Guaranteed by design.
