Product Description
Introduction
The AS7265x series integrates three chips to provide an 18-channel multispectral sensor array covering a wavelength range from 410nm to 940nm. AS72651 covers the near-infrared wavelength range from 600nm to 870nm and acts as the master controller for the entire assembly. When used in conjunction with AS72652 (with a spectral response from 560nm to 940nm) and AS72653 (with a spectral response from 410nm to 535nm), the complete system offers 18 channels with a 20nm Full Width at Half Maximum (FWHM).
Features
3-chip set providing 18 visible and near-infrared channels from 410 nanometers to 940 nanometers, with each channel having a 20-nanometer Full Width at Half Maximum (FWHM).
Integrated microcontroller on the chip with low power consumption.
Two integrated LED drivers per sensor.
Selectable UART or I²C interface.
Master-Slave-Slave sensor communication.
Stable filter conditions over temperature and lifetime.
Advantages:
Detection of spectral fingerprints in visible and near-infrared spectra.
On-chip signal processing, reducing hardware costs.
Sample illumination without the need for external LED drivers.
Easy connectivity to mobile devices or external microcontrollers.
Simplified sensor communication from a host perspective, requiring only one client.
