    Hi zgl,

    I was wondering if you could clarify on what you think the cause of the reduced range? The schematic you attached doesn't give too much information on what might be the reasoning behind the reduced range. The picture of the schematic is also low in resolution so I am unable to tell what the VDD1&2 values are as well. Also I was wondering how much did the range decrease by?

    Regards,
    Joe
