AS7265x Smart 18-Channel VIS to NIR Spectral_ID 3-Sensor Chipset
The AS7265x chipset is a sophisticated 18-channel multispectral sensor solution designed for spectral identification across the visible to near-infrared (NIR) spectrum. It comprises three devices: AS72651 (master), AS72652, and AS72653. Each sensor features six independent on-device optical filters with spectral responses ranging from 410nm to 940nm, each with a Full Width at Half Maximum (FWHM) of 20nm. This chipset integrates Gaussian filters via nano-optic deposited interference filter technology, housed in LGA packages with built-in apertures for light control. The AS7265x offers programmable LED drivers for electronic shutter applications and requires firmware loaded via a UART interface. It boasts a compact, robust design and is pre-calibrated with specific light sources, though recalibration may be necessary for different application conditions. Key benefits include a compact 18-channel spectrometry solution, no additional signal conditioning, a 16-bit ADC, and programmable LED drivers.
