Agilent HSDL-9000
Miniature Surface-Mount
Ambient Light Photo Sensor
Data Sheet
Description
The HSDL-9000 is a low cost,
digital-output ambient light photo
sensor in miniature industry-
standard PLCC lead-free surface-
mount 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 2.
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 HSDL-
9000 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 back-
lighting will benefit from
incorporating the HSDL-9000 in
their designs to reduce the power
consumption significantly.
