If not present get the
with the recommended settings and values as described in the datasheet.
Place an external resistor in Rext “I” to set the LED current. If another capacitance then 330µF 35V is needed it is possible to
disconnect the onboard capacity through the Jumper CLED “K”. Connect the LEDs with the output current drivers “J”.
Connect a voltage supply to VLED “C”. The output drivers sustain a maximum voltage of +15V at the pin.
Connect the Serial Data Interface via Line IN “D”. For the data format of the serial interface please see the datasheet of the
AS1112.
Connect a +3.0V to +5.5V power supply (VDD “A” and GND “B” or via Line IN “D”).
