... If the sensitivity is set too high for a sensor coil with bad temperature characteristics, the operating temperature range may become narrow. The operating temperature range for the whole system, including the sensor coil, can be expanded by holding down the sensitivity. Sample Recommended Operating Circuit HA16603P/FP 515 ...

... The oscillator frequency is determined by the following formula. The tank circuit formed by L and C0 has characteristic impedance shown in the figure. The condition for oscillation for the HA16603P is Rd 1/g, and the condition for oscillation to stop is Rd > 1/g. When Rd is connected to the hysteresis pin, ( and (Rd + Rh) > 1/g is the condition for oscillation to stop. Note that r hysteresis pin ...
