Ambient light sensor provides red, green, blue, and clear sensing performance

17-02-2015 | Mouser Electronics | Test & Measurement

Mouser now stocks Avago's APDS-9950 digital proximity RGB and ambient light
sensor which provides red, green, blue, and clear (RGBC) light sensing and
proximity detection.

The device detects 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, like 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 for applications
such as OLED display control, RGB LED backlight control, ambient light
colour temperature sensing, cell phone touch-screen disable, automatic
speakerphone enable, automatic menu pop-up, mechanical switch replacement
and industrial process control.
