Melexis MLX75305: Light-to-voltage sensor suits automotive industry

Joining the vendor’s SensorEyeCTM line, the MLX75305 light-to-voltage sensor suits high-volume automotive, industrial, and consumer applications. Claiming a life span exceeding 15 years, the light sensor’s output voltage varies linearly with incident light. The IC integrates the photodiode, a transimpedance amplifier, and a linear-voltage-output stage on the sensor chip. This integration allows stable light responsivity over time and over temperature and improved noise behavior, compared with designs using discrete photodiodes. Meeting AEC-Q100 automotive specifications, the devices provide a –40 to +125°C temperature range; a consumer version of the sensor is also available with an operating temperature as high as 85°C. Available in 3×3×0.65-mm DFN and SO-8 packages, the MLX75305 light-to-voltage sensor costs 30 cents (medium quantities).
