... BH1621FVC ● External parts Setting 1) Gain setting of BH1621FVC Please select the best gain controlled by 3 and 4pin based on the required illuminance range. The reference is as follows. Illuminance detection range [lx] ~1000 ~50,000 This device will be mounted under the optical window in actual designing. Therefore, there is a possibility that the illuminace to ALS ( Ambient Light Sensor ) will be less than the illuminance on the final product surface ...

... BH1621FVC ●Cautions on use 1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage ( Vmax ), temperature range of operating conditions ( Topr ), etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc ...
