HA16603P/FP
Notes
(1) An air-core coil must be used as the sensor coil.
(2) This IC has 3 ground pins. All three ground pins must be connected to ground, even if only one channel
is used.
(3) 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.
