    Hi Lokesh,

    You would need to disconnect the LEDs and the PD from the DS100A connector and connect them to the appropriate connections of the ADPD105. I don't understand why the red and IR LEDs are connected back to back on the DS100A, but the LED connections to the ADPD105 should have the cathode of the LED connected to the LEDx driver pins and the anode connected to the VLED supply. The PD cathode should be connected to the PDC pin and the PD anode should be connected to one of the PD inputs of the ADPD105.

    Regards,
