OTG Y Cable with Power to Samsung 8 Tab

[jllaudio]

I'm trying to find  OTG Cable with a Y connector that can be used to provide power to a tablet and a USB Connected DAC (Dragonfly Red).  I have tried one that provides power to the DAC but not the Tablet.  The connection I would like to have is OTG to tablet.  A Y connector (with a Regular USB and female Micro USB) on the other end with the DAC in the USB port and the regular Tablet power connector connected to the other Y connector (Female Micro USB) to provide power to both the DAC and Tablet (in this case a Samsung Galaxy 8 Tablet).

Thanks for any help
