C Interface
DESCRIPTION
VCNL4000 is a fully integrated proximity and ambient light
digital 16 bit resolution sensor in a miniature lead less
package (LLP) for surface mounting. It includes a signal
processing IC and supports an easy to use I
2
C bus
communication interface.
APPLICATIONS
• Proximity sensor for mobile devices (e.g. smart phones,
touch phones, PDA, GPS) for touch screen locking, power
saving, etc.
• Integrated ambient light function for display/keypad
contrast control and dimming of mobile devices
• Proximity/optical switch for consumer, computing and
industrial devices and displays
• Dimming control for consumer, computing and industrial
displays

PROXIMITY FUNCTION
• Built in infrared LED and photo-pin-diode for proximity
function
• 16 bit effective resolution for proximity detection range
ensures excellent cross talk immunity
• Programmable LED drive current from 10 mA to 200 mA
(in 10 mA steps)
• Excellent ambient light suppression by signal modulation
• Proximity distance up to 200 mm
AMBIENT LIGHT FUNCTION
• Built in ambient light photo-pin-diode with close to human
eye sensitivity characteristic
• 16 bit dynamic range for ambient light detection from
0.25 lx to 16 klx
• 100 Hz and 120 Hz flicker noise rejection
