A lower value increases the sensitivity. A too sensitive setting leads to

false readings because of shot noise of the receiver photo diode and the

internal amplifier (typ. input noise level is 7nA RMS without photo diode).

Also induced EMI can lead to false readings if the sensitivity is set too

low. The EMI sensitivity is heavily depending on the system architecture

and the electromechanical design. The better the shielding of the chip

and the photo diode and the better the PCB layout, the better the EMI

immunity.

The tolerance of the threshold is approx. ±25%.
