Vishay VEML4031X00 High Accuracy Ambient Light Sensor
VEML4031X00 is a high accuracy ambient light digital 16-bit resolution sensor in a miniature opaque 4.38 mm x 1.45 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 read-out is available as a digital value, and the built-in photodiode response is near that of the human eye. The 16-bit dynamic range offers ambient light detection up to about 172 klx, with a resolution down to 0.0026 lx/counts.
Besides 100 Hz and 120 Hz flicker noise rejection and a low temperature coefficient, the device consumes just 0.5 μA in shutdown mode. The sensor is AEC-Q100 qualified and has an operating range from -40 °C to +110 °C.
