Description
The ams OSRAM AS7343 is a 14-channel highly versatile, multi-purpose spectral sensor enabling
new consumer, commercial, industrial and laboratory applications. It is optimized for reflective,
transmissive and emissive measurements including color matching, fluid or reagent analysis, lateral
flow test applications and spectral identification in the visible range.
The spectral response is defined by individual channels covering approximately 380 nm to 1000 nm
with 11 channels centered in the visible spectrum (VIS), plus one near-infrared (NIR) and a clear
channel.
AS7343 integrates high-precision optical filters onto standard CMOS silicon via deposited interference
filter technology. A built-in aperture controls the light entering the sensor array to increase accuracy. A
programmable digital GPIO and LED driver enable light source and trigger/sync control. Device control
and spectral data access is implemented through 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.
