.
I
pd
soft power-down and I
pd
hard power-down are the total currents for all supplies.
I
CC
depends on the overall load at the digital pins.
I
DD(VIN)
depends on the external circuit connected to pins TX1 and TX2.
During typical circuit operation the overall current is below 100 mA.

Typical value using a complementary driver configuration and an antenna matched to 40
between TX1 and TX2 at 13.56 MHz.
