AO is an op amp-type output that does not require an external pull-down resistor. This design allows a rail-to-rail

output voltage swing. With VDD = 5 V, the output is nominally 0 V for no light input, 2 V for normal white level, and 4.8 V

for saturation light level.

When the device is not in the output phase, AO is in a high-impedance state.

The voltage developed at analog output (AO) is given by:

Vout = Vdrk + (Re) (Ee)(tint)

where:

Vout

is the analog output voltage for white condition

Vdrk

is the analog output voltage for dark condition

is the device responsivity for a given wavelength of light given in V/(μJ/cm2)

is the incident irradiance in μW/cm2

tint

is integration time in seconds

A 0.1 μF bypass capacitor should be connected between VDD and ground as close as possible to the device.
