11.4 DSBGA Light Sensitivity
Exposing the DSBGA device to direct sunlight will cause misoperation of the device. Light sources such as
Halogen lamps can also affect electrical performance if brought near to the device.
The wavelengths which have the most detrimental effect are reds and infra-reds, which means that the
fluorescent lighting used inside most buildings has very little effect on performance. A DSBGA test board was
brought to within 1 cm of a fluorescent desk lamp and the effect on the regulated output voltage was negligible,
showing a deviation of less than 0.1% from nominal.
