Ambient Light Sensor AS72652

Added to your shopping cart

The AS7265x chipset consists of three sensor devices AS72651 with master capability, AS72652 and AS72653. The multispectral sensors can be used for spectral identification in a range from visible to NIR. Every of the three sensor devices has 6 independent on-device optical filters whose spectral response is defined in a range from 410nm to 940nm with FWHM of 20nm. The AS72651, combined with the AS72652 (spectral response from 560nm to 940nm) and the AS72653 (spectral response from 410nm to 535nm) form an AS7265x 18-channel multi-spectral sensor chip-set.

Each AS7265x device has two integrated LED drivers with programmable current and can be timed for electronic shutter applications.
