DESCRIPTION

VEML7700 is a high accuracy ambient light digital 16-bit

resolution sensor in a miniature transparent 6.8 mm x

2.35 mm x 3.0 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 I2C bus communication

interface.

The ambient light result is as digital value available.

AMBIENT LIGHT FUNCTION

? FiltronTM technology adaption: close to real human eye

response

? O-TrimTM technology adoption: ALS output tolerance

≤ 10

? 16-bit dynamic range for ambient light detection from

0 lx to about 120 klx with resolution down to 0.0036 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
