Highly-integrated devices simplify optical sens

SensorEyeC devices from Melexis are integrated light sensors with a photodiode, transimpedance amplifier, output transistor and temperature compensation in one chip. The SensorEyeC series is designed to simplify optical sensing and minimise the use of external components.

The SensorEyeC series features a patented package technology that combines high robustness (including 260°C solder reflow) with an undisturbed optical path. Two open-cavity packages are available: SOIC8 and a DFN package that measures 3mm x 3mm x 0.65mm. There are also two temperature-range versions available: -20°C to 85°C and -40°C to 125°C.

The SensorEyeC series comprises the MLX75303, MLX75304 and MLX75305. The MLX75303 is an easy-to-use Schmitt-Trigger output light sensor that features a light-saturation robustness factor of 1000 to compensate for dirt.

The MLX75304 converts light intensity into an output frequency, and features a highly-linear response over a dynamical light input range of more than 100dB. The MLX75305 converts light intensity into an output voltage.

All SensorEyeC components have continuous operation lifetime qualified to over 15 years. AEC-Q100 qualified versions for automotive applications are also available.
