The Melexis SensorEyeC series are CMOS
integrated optical sensor ICs including
photodiode, transimpedance amplifier and output
transistor on one chip. These sensors are designed
for high-volume automotive and non-automotive
applications.
The MLX75305 Light-to-Voltage SensorEyeC
converts ambient or LED light intensity into an
output voltage.
The MLX75305 block diagram is shown above and
contains following blocks: a photodiode, a
transimpedance amplifier to convert and amplify
the photocurrent of the photodiode and an open
drain output buffer stage.

11. Applications Information
A typical connection diagram is shown in the figure below. A load resistor RL is needed to get the voltage level out. The load
capacitance CL is typically formed by the input capacitance of the component that is connected to the sensor output, the
wiring capacitance and the output capacitance of the sensor itself.
Figure 5
Decoupling capacitors between Vdd and Vss (1uF in parallel with 100nF) are highly recommended in all configurations.
Recommendation: every change in the application should be agreed by both parties.
