Token provides ambient light sensor for photodiode and phototransistor. For a given irradiance, the
phototransistor may show a batch change of the output current due to the susceptibility of the wafer
and the variability of the transistor gain. The lot-to-lot change of the photoelectric sensor is
significantly lower because it is only caused by the variability of photosensitivity. Token provides
phototransistor output (component) for its ambient light sensor in binned groups (Table 2). These
groups can not be ordered separately, but each reel is labeled A, B, or C, which allows the user to
select the appropriate load resistance to compensate for these wide tolerances.
