AD7893SQ-5 product support and Datsheet

I have been working with the AD7893 for a while.In order to reduce the errors associated I went with the QM version of the product, BUt there is no datasheet available regarding it. I needed to know whether we can use the QML version of the AD7893SQ-5. The QML datasheet of the AD7893 provides only the description of AD7893-SQ2 and SQ10. Please Respond or please provide the link for the datasheet .
