INTRODUCTION
The VCNL4000 is a proximity sensor with an integrated
ambient light sensor. It is the industry’s first optical sensor
to combine an infrared emitter, PIN photodiode, ambient
light sensor and signal processing IC in a single package
with a 16-bit ADC for proximity measurement as well as
ambient light measurement. The device provides ambient
light sensing to support conventional backlight and display
brightness adjustment, and proximity sensing for object and
motion detection. With a range of up to 20 cm (7.9"), this
stand-alone, single component greatly simplifies the use
and design-in of a proximity sensor in consumer and
industrial applications. The VCNL4000 features a miniature
leadless package (LLP) for surface mounting in a 3.95 mm x
3.95 mm package with a low profile of 0.75 mm designed
specifically for the low height requirements of smart phone,
mobile phone, digital camera, and tablet PC applications.
Through its standard I
allows easy access to a “proximity signal” and “light
intensity” measurement without complex calculations or
programming. For complete details on the VCNL4000
please read “Designing VCNL4000 into an Application” at
www.vishay.com/doc?83372.
ESD WARNING
The VCNL4000 is sensitive to electrostatic discharge.
Please take necessary precautions when handling the
sensor and kit.
