ams OSRAM AS7341 11-Channel Spectral Sensor Frontend
ams OSRAM AS7341 11-Channel Spectral Sensor Frontend is an 11-channel spectrometer for spectral identification and color matching applications in mobile devices. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. Six channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer.
Eight optical channels cover the visible spectrum, one channel can be used to measure near-infrared light and one channel is a photodiode without filter "clear". The device integrates a dedicated channel to detect 50Hz/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 on surrounding ambient light conditions (light source detection). The device can also be synchronized to external signals via pin GPIO.
Features
- 8x optical channels distributed over the visible range
- 3x extra channels: Clear, Flicker, and NIR channel
- 6x parallel ADCs for signal processing
- Ultra-low profile package measuring 3.1mm x 2mm x 1mm
- Spectral information enables highly accurate object color measurements
- Detection and rejection of environmental influences like light sources
- Optimized channel count and signal processing for fast measurements
- Mobile phone-compatible package
Applications
- Reflective object color sensor in mobile phones
- Color management for displays
- Ambient light flicker detection for camera assist (flicker detection)
