Claim 0:
1. An aerosol inhalation device, the aerosol inhalation device comprising:
an operational amplifier including an output terminal configured to generate a voltage according to a power applied to a load configured to heat an aerosol source and having a correlation between a temperature and an electrical resistance value;
a controller including an input terminal and configured to perform processing based on a voltage applied to the input terminal;
an RC circuit connected to the output terminal of the operational amplifier and configured to generate a voltage supplied to the input terminal of the controller;
a first switch electrically connected between the power supply and the load;
a second switch electrically connected in parallel between the power supply and the load; and
a first resistor electrically connected in series with the first switch, wherein
a power supply voltage of the operational amplifier is higher than a power supply voltage of the controller, and equals a voltage applied to an aerosol generation circuit including the load, and
one of an inverting input terminal and a noninverting input terminal of the operational amplifier is electrically connected to the aerosol generation circuit.
