RF DC and AC parameters
This section summarizes the operating and measurement conditions, and the DC and AC
characteristics of the device in RF mode. The parameters in the DC and AC Characteristic
tables that follow are derived from tests performed under the Measurement Conditions
summarized in the relevant tables. Designers should check that the operating conditions in
their circuit match the measurement conditions when relying on the quoted parameters.

1.
TA = –40 to 85 °C.
2.
All timing measurements were performed between 0 °C and 50 °C on a reference antenna with the following
characteristics:
External size: 75 mm x 48 mm
Number of turns: 5
Width of conductor: 5 mm
Space between 2 conductors: 0.3 mm
Value of the tuning capacitor in SO8: 27.5 pF (M24LR64-R)
Value of the coil: 5 µH
Tuning frequency: 13.56 MHz.
3.
Characterized only, not 100% tested
4.
15% (or more) carrier modulation index offers a better signal/noise ratio and therefore a wider operating range with a better
noise immunity
