* If the circuit is used at a frequency higher than 3MHz, it is recommended to connect a capacitor of 100pF between terminals E and D.
OPERATING MODE
Between terminals A and E, the integrated circuit
acts like a negative resistance equal to the external
resistor R1 connected between terminals B and H.
The oscillation stops when loss resistance Rp of
tuned circuit becomes smaller than R1. Then, the
supply current will be ICC = 10mA (pins G and D).
The oscillation sustains when loss resistance Rp of
tuned circuit becomes higher than R1. Then, the
supply current will be ICC 1mA (pins G and D).
Eddy currents induced by coil L1 in a metallic body,
determine loss resistance Rp.
