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

C bus communication interface.

The ambient light result is as digital value available.

AMBIENT LIGHT FUNCTION

•Filtron

technology adaption: close to real human eye

response

•O-Trim

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
