Data Sheet

Description The HSDL-9000 is a low cost, digital-output ambient light photo sensor in miniature industrystandard PLCC lead-free surfacemount package. It incorporates a photodiode, which peaks in human luminosity curve at 550 nm. Hence, it provides an excellent responsivity that is close to the response of human eyes, as shown in Figure

With the options of three digital levels and an analog Gain Control pin to fine tune the three threshold levels to achieve better sensitivity control, the HSDL9000 is ideal for applications in which the measurement of ambient light is used to control display backlighting. Mobile appliances such as mobile phones and PDAs that draw heavy current from the display backlighting will benefit from incorporating the HSDL-9000 in their designs to reduce the power consumption significantly.
