General Description

General Description
The ams AS7341 is an 11-channel spectrometer enabling new consumer, commercial and laboratory
applications including spectral identification, reflection and absorption for color matching, fluid or
reagent analysis, passive ambient light measurement and color calibration. The spectral response is
defined by individual channels covering approximately 350nm to 1000nm with 8 channels centered in
the visible spectrum (VIS), plus one near-infrared (NIR) and a clear channel. The NIR channel in
combination with the other VIS channels may provide information of surrounding ambient light
conditions, including light source detection. Light source detection can be assisted by an integrated
flicker channel that can automatically flag ambient light flicker at 50/60Hz as well as buffer data for
externally calculating other flicker frequencies up to 2kHz.
AS7341 integrates high-precision optical filters onto standard CMOS silicon via nano-optic deposited
interference filter technology. A built-in aperture controls the light entering the sensor array to increase
accuracy. A programmable digital GPIO and LED current controller enable light source and trigger
control, as well as enabling expandability for an added external photodiode. 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 3.1mm x 2mm x 1mm.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to
the device. These are stress ratings only. Functional operation of the device at these or any other
conditions beyond those indicated under “Operating Conditions” is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability. All voltages with respect
to GND/PGND. Device parameters are guaranteed at VDD=1.8V and TA=25°C unless otherwise noted.
