Note for equation (5): Mind that the quality factor of the antenna (Q
and the quality factor of the capacitance as:
(9)
So, a capacitance with a low quality factor may also reduce the antenna impedance.
9 Typical configuration: READ ONLY
The MLX90109 is a highly integrated reader IC. In the application schematic below, only two resistors to set
V
for a better noise cancellation.
The interface with the microcontroller can be realized with only one connection. In this case, the mode pin is
left floating and the integrated decoding is not used.
