General description

AS7341L is a 10-channel spectrometer for spectral identification and analytic applications used in mobile devices. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 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”). The NIR channel in combination with the other VIS channels may provide information about special characteristics of analytes (e.g. Lateral Flow Tests).
The device can also be synchronized to external signals via pin GPIO.

AS7341L integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array.
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.

AS7341 – 11-Channel Spectral Color Sensor

AS7341

AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 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”). The device also integrates a dedicated channel to detect 50Hz or 60Hz ambient light flicker. The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The NIR channel in combination with the other VIS channel may provide information of surrounding ambient light conditions (light source detection). The device can also be synchronized to external signals via pin GPIO.
AS7341 integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array.
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.

Point of Care Diagnostics

Fast test and results performed at the patient's location, instead of at a laboratory, will lead to higher quality of care. Locally administered diagnostic services provide many advantages including a shorter waiting time for results and reduced cost. Chip-scale integration and miniaturization are critical elements in the design of successful point of care diagnostic equipment – especially when linked to medical-certified cloud services at the time of international pandemic.

As a global leader in optical technology and sensors, our optical sensor technologies support the development of next-generation point of care systems including light detectors, light sources, on-wafer filter technologies and micro-optics lens systems. ams' optical sensor products are available as chips and as optical modules with the modules including light sources and detectors for easy integration into end product designs.
