Table 12. Advantages and Disadvantages of Non Destructive Readout
Sequencer
The sequencer generates the complete internal timing of the
pixel array and the readout. The timing can be controlled by the
user through the SPI register settings. The sequencer operates

Low noise because it is a true CDS.
High sensitivity because the conversion capacitance is kept
rather low.
High dynamic range because the results includes signal for
short and long integrations times.

System memory required to record the reset level and the interme-
diate samples.
Requires multiples readings of each pixel, thus higher data
throughput.
Requires system level digital calculations.
