AS7262
6-Channel Visible Spectral_ID Device
with Electronic Shutter and Smart
Interface
General Description
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.
