*8: No dew condensation

When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation

may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.

Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the

product within the absolute maximum ratings.

A/D output is the output with dark output is

subtracted when light is input. The difference

between the ideal value and typical example

contains a measurement error. The smaller the

A/D output, the larger the measurement error.
