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.
