'Industry’s first' high temperature digital ambient light sensor

Designed to support continuous operation up to 105°C, the ISL76683 is qualified to the Automotive Electronics Council's AEC-Q100 grade 2 and maintains package transparency under automotive thermal stress. Available now in 4.2mm2 6pin OFDN packaging, Intersil claims the device provides an optimal solution for measuring light levels in a variety of automotive applications, including flat panel display backlighting, courtesy lighting control and temperature sensitive windshield applications. In addition, the integrated 16bit analogue to digital converter core is designed to provide on chip sensor signal conditioning along with user programmable sensitivity to tailor performance for specific lighting conditions. The ISL76683 also features built in rejection of infrared and ultraviolet light to provide a 'close to human eye' sensitivity (lambda response), as well as 50 and 60Hz flicker elimination technology. The sensor is temperature compensated, removing the requirement to compensate for the vehicle's thermal environment. In addition, light level thresholds are programmable via I2C, enabling designers to set up an automatic monitoring system while simultaneously reducing system level control overhead.
