VEML6035 - New Ambient Light Sensor for Wearables and Smartphones

VEML6035 - Low Power, High Sensitivity Ambient Light Sensor
VEML6035 - Low Power, High Sensitivity Ambient Light Sensor

Vishay Intertechnology has released a new space-saving ambient light sensor VEML6035 for small form factor applications such as smart watches and sport bands where very high sensitivity is needed to allow light to be sensed through an often very dark cover glass. The VEML6035 ambient light sensor features a very high sensitive photo-diode, low-noise amplifier, and 16-bit ADC in a miniature low profile, transparent surface-mount package measuring only 2 mm x 2 mm x 0.4 mm. The device small size profile will help in many design options for display management in space-constrained designs. To eliminate loading on the host, the sensor uses an active interrupt function that is triggered outside the threshold window settings. 


The VEML6035 sensor features Filtron wafer-level optical filter technology which will enable ambient light spectral sensitivity close to that of the human eye. The device can operate in applications with low-transmittance (dark) lens designs since it features detection with highly linear behavior from 0.004 lx to 6710 lx and resolution down to 0.0004 lx/ct. The 100 Hz and 120 Hz flicker noise rejection and excellent temperature compensation helps it to maintain stability despite changes in ambient temperature.
