Operation with the shutter function
Integration can be stopped at any time via pin DIS,
i.e. the photodiodes are disconnected from their cor-
responding integration capacitor when DIS is high and

the current integration capacitor voltages are main-
tained. If this pin is open or switched to GND the pixel
photocurrents are summed up by the integration ca-
pacitors until the next successive SI signal follows.

External bias current setting
In order to reduce the power consumption of the device
an external reference current can be supplied to pin
RSET which reduces the maximum readout frequency,
however. To this end a resistor must be connected
from VCC to RSET. If this pin is not used, it should
be connected to GND.
