4. General Description
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.
