摘要： An analog/digital converter has a charge circuit that has a charge capacitor storing an electric charge commensurate with an input current, and first and second discharge circuits that discharge the electric charge stored in the charge capacitor. While the charge capacitor is charged for a predetermined charge period, every time a predetermined amount of electric charge is stored in the charge capacitor, the electric charge stored there is discharged by the first discharge circuit. After the charge period, the electric charge remaining in the charge capacitor is discharged by the second discharge circuit. Based on the number of discharges performed by the first discharge circuit and the discharge duration of the second discharge circuit, a digital value of the voltage commensurate with the amount of electric charge with which the charge capacitor has been charged is outputted. This offers a wider input dynamic range combined with an enhanced minimum resolution without requiring complicated external control, and in addition allows measurement to be performed in less time.

摘要： In an illuminance sensor, a photoelectric converter (1) includes three photosensors (PS), and each photosensor (PS) outputs a current as a difference between photocurrents generated in two photodiodes (PDA, PDB) having different light reception characteristics. Ratios between light receiving areas of the two photodiodes (PDA, PDB) in the three photosensors (PS) are different from each other, and the sum of positive currents among output currents of the three photosensors (PS) is constant for a given illuminance, regardless of the type of light source. A computation control unit (7) obtains illuminance based on the sum of the positive currents among the output currents of the three photosensors (PS).
