DESCRIPTION
VEML7700 is a high accuracy ambient light digital 16-bit
resolution sensor in a miniature transparent 6.8 mm x
3.0 mm x 2.5 mm package. It includes a high sensitive photo
diode, a low noise amplifier, a 16-bit A/D converter and
supports an easy to use I
2
C bus communication interface.
The ambient light result is as digital value available.
FEATURES

technology adaption: close to real human eye
response
•O-Trim
TM
technology adoption: ALS output tolerance
≤ 10 %
• 16-bit dynamic range for ambient light detection from
0 lx to about 167 klx with resolution down to 0.005 lx/ct,
supports low transmittance (dark) lens design
• 100 Hz and 120 Hz flicker noise rejection
• Excellent temperature compensation
• High dynamic detection resolution
• Software shutdown mode control
APPLICATIONS
• Ambient light sensor for backlight dimming of e.g. TV
displays, smart phones, touch phones, PDA, GPS
• Ambient light sensor for industrial on- / off-lighting
operation
• Optical switch for consumer, computing, and industrial
devices and displays
