APDS-9005

Miniature Surface-Mount Ambient Light Photo Sensor

Data Sheet

Description

The APDS-9005 is a low cost analog-output ambient
light photo sensor in miniature chipLED lead-free surface
mount package. It consists of a photo sensor, whose
spectral response is close to the CIE standard photopic
observer, as show in gure 2. The APDS-9005 is ideal for
applications in which the measurement of ambient light
is used to control display backlighting. Mobile applianc­es such as the mobile phones and PDAs that draw heavy
current from display backlighting will benet from incor­porating these photo sensor products in their designs by
reducing power consumption signicantly.

Application Support Information

The Application Engineering Group is available to assist
you with the application design associated with APDS­9005 ambient light photo sensor module. You can
contact them through your local sales representatives for
additional details.
