Looking at the PDF datasheet, the output is VO+ & VO-
They are in opposite phase. In fact if you scope the waveform from pins 6 & 12 the resulting output is double. You can use a centre tapped tx and use the centre tap as the supply..... But it needs to be decoupled and distortion is huge. In the data sheet for various applications I see no centre tapped tx. I tried feeding a transistor buffer in many ways but the end result seems to be best for me.
I will though try it again with the centre tap direct to supply, as I fed it via a 1.6k resistor decoupled by 4.7nf.
