The setting value of the substrate voltage (V
SUB
) is indicated on the back of the image sensor by a
special code. When adjusting the substrate voltage externally, adjust the substrate voltage to the indicated
voltage. The adjustment precision is ±3%. However, this setting value has not significance when used in
substrate bias internal generation mode.
