Abstract:
The present invention provides a sensor device and an electronic apparatus each of which does not make malfunction derived from outside ambient light such as sunlight. In the sensor device, an ADC outputs, to one of two input terminals of a comparison circuit, second data which is a digital value ADCOUT corresponding to a current Iin−I1 being the result of subtraction from a current I1 from a current Iin and which is larger than a threshold Data_th.
