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. 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. 390107530501 Rev. xxx Page 6 of 10 Data Sheet July/07 MLX75305 Light-to-Voltage Converter 8 SO8 Open Cavity Package Information SO8 open cavity package, MSL3, 260˚C soldering profile (target). 390107530501 Rev. xxx Page 7 of 10 Data Sheet July/07 MLX75305 Light-to-Voltage Converter 9 DFN3x3 Open Cavity Package Information DFN3x3 open cavity package, MSL3, 260˚C soldering profile (target). 390107530501 Rev. xxx Page 8 of 10 Data Sheet July/07 MLX75305 Light-to-Voltage Converter 10 Standard information regarding manufacturability products with different soldering processes of Melexis Our products are classified and qualified regarding soldering technology, solderability and moisture sensitivity level according to following test methods: Reflow Soldering SMD’s (Surface Mount Devices) • • IPC/JEDEC J-STD-020 Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices (classification reflow profiles according to table 5-2) EIA/JEDEC JESD22-A113 Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing (reflow profiles according to table 2) Wave Soldering SMD’s (Surface Mount Devices) • EN60749-20 Resistance of plastic- encapsulated SMD’s to combined effect of moisture and soldering heat Solderability SMD’s (Surface Mount Devices) • EIA/JEDEC JESD22-B102 and EN60749-21 Solderability For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis.
