AS72651 Datasheet | ams

Description The AS72651 is a digital 6-channel multi-spectral sensor for spectral identification in the near IR light wavelengths, serving as master controller for the AS7265x chip-set. It has 6 independent on-device optical filters whose spectral response is defined in the NIR wavelengths from 600nm to 870nm with FWHM of 20nm. The AS72651, bined 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 from 410nm to 940nm. Each AS7265x device has two integrated LED drivers with programmable current and can be timed for electronic shutter applications. The device family integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology in LGA packages that also provide built-in apertures to control the light entering the sensor array.
