Agilent APDS-9002
Miniature Surface-Mount
Ambient Light Photo Sensor
Data Sheet
Description
The APDS-9002 is a low-cost
analog-output ambient light
photo sensor in lowest cost
miniature chipLED lead-free
surface mount package. It
consists of a spectrally suited
phototransistor, which peaks in
human luminosity curve. Hence,
it provides an excellent
responsivity that is close to the
response of human eyes, as
shown in Figure 2. It provides a
design-alternative to the
HSDL-9000 digital-output
ambient light photo sensor is
suitable for portable
applications with its ultra small
package design.
The APDS-9002 is ideal for
applications in which the
measurement of ambient light is
used to control display back-
lighting. Mobile appliances such
as the mobile phones and PDAs
that draw heavy current from
display backlighting will benefit
from incorporating these photo
sensor products in their designs
by reducing power consumption
significantly.
