(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Tank quality factor

(1)

The coil inductance of the antenna LRES together with the external capacitance CTune plus the device internal capacitance CIN is a

resonant circuit. The resonant frequency of this LC circuit must be close to the carrier frequency fc:

fRES = 1 / [2π(LRESCRES)

1/2] = 1 / [2π(L

RES(CIN + CTune))

1/2] ≈ f

(2)

For CIN refer to Section 4.12.
