AS7262

6-Channel Visible Spectral_ID Device

with Electronic Shutter and Smart

Interface

The AS7262 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 that provides a built in

aperture to control the light entering the sensor array.

Control and spectral data access is implemented through either

the I²C register set, or with a high level AT Spectral Command

set via a serial UART.

Ordering Information and Content Guide appear at end of

datasheet.
