TCS3430 sensor IC is smallest, says ams
TCS3430 sensor IC is smallest, says ams: Advanced optical filter technology is used in the TCS3430 sensor integrated circuit (IC). The technology produces illuminance and correlated colour temperature (CCT) measurements that closely match the response of the human eye, claims ams.
It is says ams, the first XYZ tristimulus True Color sensor IC to be offered with a small footprint suitable for consumer devices such as notebooks, smartphones and tablets. Providing digital measurements of illuminance (brightness) and chromaticity matching the CIE 1931 Standard Observer XYZ scale enabling True Color functionalities – which is the industry standard for quantifying the average human’s perception of light. The miniature TCS3430 may be used for display management, automatic white colour balancing or colour management.
Original equipment manufacturers (OEMs) which move from RGB colour sensors to the cost-effective TCS3430 will be able to achieve dramatic improvements in camera and display performance, says ams. The IC can be used by users of mobile devices to adapt the display colour and brightness towards warm or cool white, based on the CCT level of the environment. It also enables display calibration to provide colour balancing and vivid images based on the source input.
Another characteristic, says ams is more realistic images and almost zero colour distortion from the camera, rivalling the colour balancing performance of professional-grade photography equipment.
The TCS3430 uses proprietary ams technology for fabricating interferometric optical filters directly on the wafer. The ams interferometric filters can be made with the spectral characteristics of the XYZ spectral responsivity model of the human eye. In the TCS3430, the filters provide five channels: X, Y and Z channels and two infra red (IR) channels. The IR channels are used for advanced light source detection. The Y channel’s response to the green portion of the visible light spectrum provides a measure of illuminance, enabling the TCS3430 to operate as an ambient light sensor as well as a colour sensor.
The TCS3430 is supplied as a packaged IC measuring 2.41 x 1.75 x 1.00mm. The aperture of the sensor needs to be covered by an achromatic diffuser. The TCS3430’s sensitivity and wide dynamic range mean that it can be mounted behind dark or transparent cover glass. It operates from a 1.8V supply, and provides an inter-integrated circuit (I2C) interface to a host processor.
The TCS3430 is the smallest available True Color sensor, claims ams. Kevin Jensen, senior marketing manager for Color Sensors at ams explains: “Recent surveys confirm that consumers find it challenging to match items from their home to store or online products. The precise white point balancing of images does not only improve the quality of images for designers and professionals, but also assists general consumers to make decisions and reduce overall product returns”, he says.
The TCS3430 is available for sampling and the TCS3430 evaluation kit is also available.
