APDS-9801
Digital Proximity and Analog Ambient Light Sensor
Data Sheet
Description
APDS-9801 is a module that integrates functions of an
Analog ambient light sensor (ALS) and a proximity sensor
(PS). The sensor has four chips in one small package: an
ambient light sensor IC, proximity sensor signal condition-
ing circuitry and a proximity sensor that includes both an
emitter and detector. The Analog ambient light sensor
has current output, with spectral response close to the CIE
standard Photopic observer. The proximity sensor IC has a
LED driver and receiver circuit with digital count output,
featuring excellent ambient light cancellation capabil-
ity. With the built-in LED, the proximity sensor is able to
sense the proximity of an object, such as finger or head to
a portable device.
Ambient light sensors can be used to control the bright-
ness of display backlighting by detecting the ambient
light illuminance level. Proximity sensor technology make
possible applications where detection or proximity of a
user’s head in relationship to display will turn off/on the
keypad and LCD backlight. The combination of ambient
light sensors and proximity sensors in one module make
it ideal for portable devices, such as mobile phone, PDA
and notebooks.
