Description

The AS7265x family incorporates 3 chips to deliver an 18-channel multi-spectral sensing array covering wavelengths from 410nm to 940nm. The AS72651 covers NIR wavelengths from 600nm to 870nm and serves as the master controller for the set. When combined with the AS72652 (spectral response from 560nm to 940nm) and the AS72653 (spectral response from 410nm to 535nm) the full set delivers 18-channels with FWHM of 20nm. The device family integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology in LGA packages, and each AS7265x device has two integrated LED drivers with programmable current and which can be timed for electronic shutter applications.
