ams AS7341L - 10-Channel Spectral Analytic Sensor

The TCS3448 is a 14-channel highly versatile, multi-purpose spectral light sensor. It is optimized to sense spectral components of ambient light in the visible range. Such spectral information is used for camera enhancement (CCT, AWB, exposure time). 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. Applications can be assisted to allow classification of ambient light and an integrated flicker detection channel that can automatically flag ambient light flicker at 50/60 Hz as well as buffer data for externally calculating other flicker frequencies. TCS3448 integrates high-precision optical interference filters directly deposited on photodiodes which are embedded in CMOS silicon. 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 1.2 V/1.8 V interface. The device is available in an ultra-low profile package with dimensions of 3.1 mm x 2 mm x 1 mm.
