APDS-9800
Integrated Ambient Light and Proximity Sensor
Data Sheet
Description
Features
The APDS-9800 integrates ambient light sensor (ALS), ꢀ Integrated module with ambient light sensor, proximity
proximity sensor (PS) and ambient light cancelation
functions in a single module. The module contains three
chips in one small package: an ambient light sensor
IC, a proximity sensor signal conditioning circuit and a
sensor and signal conditioning IC
ꢀ Small form factor: L 4.95 x W 3.0 x H 1.45 mm
ꢀ Supply voltage range: 2.4 V to 3.6 V
proximity sensor that includes both an LED emitter and ꢀ Spectral responsivity closely matches the human eye
detector.
ꢀ Built-in LED and detector for proximity detection
The ambient light sensor has a spectral response close to
the CIE standard photopic observer and a current output.
ꢀ Low sensitivity variation across various light sources
ꢀ Linear output across a wide illumination range
ꢀ Operates under strong sunlight and artificial light
The proximity sensor signal conditioning circuit has an
LED driver and a receiver circuit that has both analog and
digital outputs. With the built-in LED, the proximity sensor
is able to sense the proximity of an object, such as a finger,

hand or head that is close to a portable device. The PS also ꢀ Controlled output voltage and integration time with
features an excellent ambient light cancellation circuit for
operation in direct sunlight.
an external resistor and capacitor
ꢀ LED stuck High protection
By detecting the ambient light illuminance level, the
ambient light sensor can control the brightness of display
backlights.
ꢀ Both analog and digital outputs available
ꢀ Shutdown mode for low current consumption
ꢀ Lead-free and RoHS compliant
The proximity sensor makes many interesting and useful
applications possible. For example, a proximity sensor
can detect the proximity of a mobile phone user’s head
and turn off or on the phone keypad and LCD backlight.
Applications
ꢀ PDAs
ꢀ Mobile phones
By combining an ambient light sensor and proximity
sensor in a single compact module, mobile phones, PDAs
and notebooks can have additional features or benefit
from increased performance, such as in battery life.
ꢀ Portable and handheld devices
ꢀ Personal computers, netbooks and notebooks
ꢀ Amusement products
ꢀ Games
ꢀ Vending Machines
