General Description

AS7341L1 is a 10-channel spectrometer for spectral identification and color matching for lateral flow

and health related devices. The AS7341L part number enables developers the use ams-related

propriety technology related to the lateral flow principle. The spectral response is defined in the

wavelengths from approximately 350 nm to 1000 nm. 6 channels can be processed in parallel by

independent ADCs while the other channels are accessible via a multiplexer. 8 optical channels cover

the visible spectrum, one channel can be used to measure near infra-red light and one channel is a

photo diode without filter (“clear”). This enables to readout the spectral information of a color strip and

enables multi-analyte detection or fluorescent-based measurement capabilities. The NIR channel in

combination with the other VIS channel may provide additional spectral information. The device can

be synchronized to external signals via pin GPIO.

AS7341L integrates filters into standard CMOS silicon via nano-optic deposited interference filter

technology and its package provides a built in aperture to control the light entering the sensor array.

Control and spectral data access is implemented via a serial I²C interface. The device is available in

an ultra-low profile package with dimensions of 3.1 mm x 2 mm x 1 mm.
