LED-BACKLIGHT
3 different variants are available for individual backlighting:
white, amber and a duo-color green/red version.
There are 2 separate LED paths available for each
monochrome backlight that can be switched in parallel or
in series to suit the system voltage. This means that most
backlights can be run at either 3.3 V or a higher voltage.
To operate the backlight, we recommend a current source
(e.g. CAT4238TD) or an external series resistor to limit
the current. This can be calculated from R=U/I; you can
find the values in the table on the right. To prolong the life
of the backlights, we recommend that you use a current

source.
Connected in parallel
The operating life of the amber and green/red backlights
is 100,000 hours. The life of the white backlight is ^{Connected in series}
considerably shorter. We recommend that you dim these
or switch them off whenever possible.

Important:
Do never connect the backlight LEDs directly to a
5 V/3.3 V supply as this will immediately destroy
the LEDs.Always use a current source. Please note
that derating applies at temperatures exceeding
+25°C.
