High Accuracy Ambient Light Sensor With I2C Interface

DESCRIPTION VEML6030 is a high accuracy ambient light digital 16-bit resolution sensor in a miniature transparent 2 mm x 2 mm package. It includes a high sensitive photodiode, a low noise amplifier, a 16-bit A/D converter and supports an easy to use I2C bus communication interface and additional interrupt feature.

The ambient light result is as digital value available.

APPLICATIONS

? Ambient light sensor for mobile devices (e.g. smart phones, touch phones, PDA, GPS) for backlight dimming

? Ambient light sensor for industrial on- / off-lighting operation

? Optical switch for consumer, computing, and industrial devices and displays

FEATURES ? Package type: surface-mount ? Dimensions (L x W x H in mm): 2 x 2 x 0.87 ? Integrated modules: ambient light sensor (ALS) ? Supply voltage range VDD: 2.5 V to 3.6 V ? Communication via I2C interface ? I2C bus H-level range: 1.7 V to 3.6 V ? Floor life: 72 h, MSL 4, according to J-STD-020 ? Low stand by current consumption: typ. 0.5 A ? Material categorization: for definitions of

compliance please see doc?99912

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
