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.

13. Standard Information
Our products are classified and qualified regarding soldering technology, solderability and moisture
sensitivity level according to standards in place in Semiconductor industry.
For further details about test method references and for compliance verification of selected soldering
method for product integration, Melexis recommends reviewing on our web site the General
Guidelines soldering recommendation. For all soldering technologies deviating from the one mentioned in
above document (regarding peak temperature, temperature gradient, temperature profile etc), additional
classification and qualification tests have to be agreed upon with Melexis.
For package technology embedding trim and form post-delivery capability, Melexis recommends to consult
the dedicated trim&form recommendation application note: lead trimming and forming recommendations
Melexis is contributing to global environmental conservation by promoting lead free solutions. For more
information on qualifications of RoHS compliant products (RoHS = European directive on the Restriction Of
the use of certain Hazardous Substances) please visit the quality page on our
website: http://www.melexis.com/en/quality-environment
