ADPD2211 sensitivity

I have found figure 5, thanks :-)

As it turns out there is no direct "sensitivity" metric for analog sensors.  For the ADPD2211 you need to look at both sides of the SNR equation.  On the "S" side of the equation we look at responsivity.  This tells the user how much signal they will receive for a given amount of light as specified in optical power.  This is called the responsivity and is measured in amps of input photodiode current per watt of optical power at a specific wavelength or (A/W).  Recall that the energy of a phone for a given wavelength is h*c/lambda, and that energy integrated over time is power.  On the noise side we can look at the noise floor of the sensor as a function of frequency.  The more one averages the lower the lower the noise floor until one reaches the "noise corner of the system".  The ADPD2211 has no measurable noise corner and its noise floor is ~80fA/sqrt(Hz).  If you want the noise floor in terms of an average you will then need to multiply the 80fA/sqrt(Hz) by the square root of the effective bandwidth of the measurement.
