APPLICATION INFORMATION
Power Supply Considerations
For optimum device performance, power-supply lines should be decoupled by a 0.01-
μ
F to 0.1-
μ
F capacitor
with short leads connected between VDD and GND mounted close to the device package.
Device Operational Details
The voltage developed at the output pin (OUT) is given by:
V
O
= V
D
+ (R
e
) (E
e
)
where:
V
O
V
D
R
e
E
e
is the output voltage
is the output voltage for dark condition (E
e
= 0)
is the device responsivity for a given wavelength of light given in mV/(
μ
W/cm
2
)
is the incident irradiance in
μ
W/cm
2
V
D
is a fixed offset voltage resulting primarily from the input offset voltage of the internal op amp. As shown in
the equation above, this voltage represents a constant, light-independent term in the total output voltage V
O
.
At low light levels, this offset voltage can be a significant percentage of V
O
. For optimum performance of any
given device over the full output range, the value of V
D
should be measured (in the absence of light) and later
subtracted from all subsequent light measurements (see Figures 2 and 3).
