depends on the overall load at the digital pins.
[6] I
DD(TVDD)
depends on V
DD(TVDD)
and the external circuit connected to pins TX1 and TX2.
[7] During typical circuit operation, the overall current is below 100 mA.
[8] Typical value using a complementary driver configuration and an antenna matched to 40  between pins TX1 and TX2 at 13.56 MHz.
