This will remove the interference ripples in the figure above. With this special Anti Reflection Coating, the sensitivity curve in function of wavelength will be somewhat lower (typically 4%) but will no longer display interference ripples. 7 Timing diagrams Definition of the switch-on and switch-off thresholds 390107530301 Rev. 001 Definition of the switch-on and switch-off delays Page 7 of 13 Data Sheet Mar/08 MLX75303 Optical Switch SensorEyeC Definition of the light pulse duration Definition of the power-on delay 8 Test diagrams Measurement and trimming of Eeon, Eeoff and hysteresis: 390107530301 Rev. 001 Page 8 of 13 Data Sheet Mar/08 MLX75303 Optical Switch SensorEyeC Functional check of Eeon and Eeoff thresholds and timing measurements (Go-NoGo tests): 9 Applications Information A typical connection diagram is shown in the figure below. A load resistor RL is needed to get a 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. Vdd Ee RL OUT MLX75303 CL 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. 390107530301 Rev. 001 Page 9 of 13 Data Sheet Mar/08 MLX75303 Optical Switch SensorEyeC 10 DFN3x3 Open Cavity Package Information DFN3x3 open cavity package, MSL3, 260˚C soldering profile (target).
