Spectral Responsivity Curve
Typical Photodiode Spectral Response Curve (%), without Anti
Reflection Coating*
*There is also an option for an
Anti Reflection Coating
. 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.

8 Applications Information
A typical connection diagram is shown in the figure below. A load resistor R
L
is needed to get a voltage level
out. The load capacitance C
L
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.
