ams OSRAM AS7262 6-Channel VIS Sensor

ams OSRAM AS7262 6-Channel VIS (Visible Spectral_ID) Sensor with electronic shutter and smart interface is a cost-effective multi-spectral sensor-on-chip solution designed to address spectral ID applications. This highly integrated device delivers 6-channel multi-spectral sensing in the visible wavelengths from approximately 430nm to 670nm with full-width half-max (FWHM) of 40nm. An integrated LED driver with programmable current is provided for electronic shutter applications.

The AS7262 integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in an LGA package. This package provides a built in aperture to control the light entering the sensor array. Control and spectra data access is implemented through either the I2C register set, or with a high level AT Spectral Command set via a serial UART. Typical applications include portable spectrometry, horticulture, color matching and identification, authentication and brand protection, and precision color tuning/calibration.

The ams OSRAM AS7262 6-Channel VIS Sensor is housed in a compact 4.5mm x 4.7mm x 2.5mm LGA-20 package.
