DAC904 transformer configuaration

HI

My customer would like to use the DAC904  with the following configuration :

"IOUTshould be set to20mA.
Forthe generation of asingle-endedsignalwe want to usea50 ohmADT2-1T(2:1Transformer).
The output voltageisin one casebe + / -1V, otherwise0 ..2V.
IwouldIOUTandIOUT_inv(andnotin acase, thecentertapto GND,in the other case), each with50ohmsto AGNDwired
Then would by a2:1Transformer the outputvoltagesachieved?"

regards,

kamal
