[1] Supply voltages below 3 V reduce the performance in, for example, the achievable operating distance.

[2] VDDA, VDDD and VDD(TVDD) must always be the same voltage.

[3] VDD(PVDD) must always be the same or lower voltage than VDDD.

[4] Ipd is the total current for all supplies.

[5] IDD(PVDD) depends on the overall load at the digital pins.

[6] IDD(TVDD) depends on VDD(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 Ω between pins TX1 and TX2 at 13.56 MHz.
