Note 1: The sensitivity is defined as the minimum amplitude
of the 2kHz- modulation, generated by the transponder,
demodulated and decoded by the reader. This parameter
depends on the application:
the value of VDD
the antenna
the code sent to the reader
Note 2: The antenna amplitude voltage is:
Vant = VDD – VMODU + Vos
Note 3: The supply current of the device depends on the
antenna drive current IDD,ant:
Typically: IDD 1.3 mA + IDD,ant / 6.3
Note 4: The antenna supply current (called IDD,ant) is the
equivalent DC supply current driven by the chip through the
antenna.
