The maximum currents mentioned in
the maximum supply current for Vpix.
It is important to notice that we don't do any power supply filtering on chip and that noise on these power supplies can contribute
immediately to the noise on the signal. Especially the voltage supplies Vpix and Vdda are important to be well noise free. With respect
to the power supply Voo, a special decoupling is used, for which an additional power supply Vstable is required.

of Vpix are destroyed the sensor isn't operating normally and will not meet the described specifications.
