ams AS7225
The AS7225 Smart Lighting Director incorporates an embedded digital tri-stimulus chromatic ‘calibrated for life’ nano-optic sensor providing direct CIE1931 XYZ and CIE 1976 u’v’ coordinate mapping. The AS7225 arrives pre-calibrated, and is designed for rapid integration into white-tunable and daylight responsive luminaire designs, delivering directives to the local microprocessor via an industry-standard I²C bus. The AS7225 integrates standard-observer filters onto the silicon via nano-optic deposited interference filters which deliver high-stability over time and temperature.| Part No. | AS7225 |

GENERAL DESCRIPTION
Adaptive algorithmic support enables a companion microprocessor to implement closed-loop, autonomous adjustment of variable CCT and daylight responsive LED lamps and luminaires. An additional on-chip I²C master provides native support for select ams sensors, such as the TSL4531 for combining in-looking CCT tunable director functions with outward-looking ambient light sensing and daylighting control. The LGA package includes a built in aperture to control light entering the sensor array. Integrated intelligence enables lifetime CCT calibration to within 2-4 Macadam steps.
