APDS-9950
Digital Proximity, RGB and Ambient Light Sensor
Data Sheet
Description
The APDS-9950 device provides red, green, blue, and clear
(RGBC) light sensing and proximity detection. The devices
detect light intensity under a variety of lighting conditions
and through a variety of attenuation materials, including
dark glass. The proximity detection feature allows a
large dynamic range of operation for accurate distance
detection, such as in a cell phone, for detecting when the
user positions the phone close to their ear. IR LED sink
current is factory-trimmed to provide consistent proximity
response without requiring customer calibrations. An
internal state machine provides the ability to put the
device into a low power state in between proximity and
RGBC measurements, providing very low average power
consumption.
The color-sensing feature is useful in applications such as
LED RGB backlight control, solid-state lighting, reflected
LED color sampler, or fluorescent light color temperature
detection. The integrated IR blocking filter makes this
device an excellent ambient light sensor and color
temperature monitor sensor.
