Figure 15. Typical Dynamic Range for Different Operating Conditions
The dynamic range is defined by the ratio of the saturation level to the temporal rms
noise in darkness.
The increase of dynamic range with the vertical frequency is due to the reduction of dark
current when the vertical frequency increases (in particular reduction of transfer time
where the device is no longer in the MPP mode).
For output frequencies lower than 20 MHz/output, it is recommended to cut-off the out-
put amplifier bandwidth by means of an off chip capacitance so as to minimize amplifier
noise. To do so the output amplifier bandwidth has to be adjusted at 5 times the output
frequency. The results given above take into account this optimization of amplifier noise.
