ams OSRAM AS7265x Smart Spectral Sensors

ams OSRAM AS7265x Smart Spectral Sensors consists of three sensor devices AS72651 with master capability, AS72652, and AS72653. The multi-spectral sensors can be used for spectral identification in a range from visible to NIR. Using the AS7265x chipset requires the use of firmware. The AS7265x 18-channel multi-spectral sensor chipset ranges from 410nm to 940nm. Each AS7265x device has two integrated LED drivers with programmable current and can be timed for electronic shutter applications. Features include a UART or I2C slave digital interface, 16-bit ADC with digital access, and programmable LED drivers. Typical applications include horticultural and specialty lighting, product/brand authentication, anti-counterfeiting, and portable spectroscopy.
