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. Using the AS7265x chipset requires the use of firmware. It must be loaded into a serial flash via a UART interface. The components AS72651, AS72652 and AS72653 are pre-calibrated with a specific light source. The information about the conditions of the performed calibration (for example light source, gain, integration time) can be found in the table of optical characteristics of the respective component. Any operation other than these conditions might require a new calibration in the application.
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.
