NOTES:  3.  Measurements are made with R
L
= 10 k?between output and ground.
4.  Optical measurements are made using small-angle incident radiation from an LED optical source.
5.  The 640 nm input irradiance E
e
is supplied by an AlInGaP LED with peak wavelength ?/DIV>
p
= 640 nm.
6.  Irradiance responsivity is characterized over the range V
O
= 0.2 to 4 V. The best-fit straight line of Output Voltage V
O
versus
irradiance E
e
over this range may have a positive or negative extrapolated V
O
value for E
e
= 0. For low irradiance values, the output
voltage V
O
versus irradiance E
e
characteristic is non linear with a deviation toward V
O
= 0, E
e
= 0 origin from the best-fit straight
line referenced above.
