Preliminary data sheet
10.20.1 Basic output configuration
Where:
The use of a differentially coupled transformer output (see Figure 29) provides optimum
distortion performance. In addition, it helps to match the impedance and provides
electrical isolation.
The DAC1617D1G0 can operate a differential output of up to 2 V (p-p). In this
configuration, connect the center tap of the transformer to a 33  resistor, which is
connected to the 3.3 V analog power supply. This adjusts the DC common-mode to
around 2.8 V (see Figure 30).
