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.
