10.13.1 Basic output configuration
10.13 Output configuration
The use of a differentially-coupled transformer output provides optimum distortion
performance (see
electrical isolation.
The DAC1008D650 can operate at a V
configuration, it is recommended to connect the center tap of the transformer to a 62 Ω
resistor connected to the 3.3 V analog power supply, in order to adjust the DC
common-mode to approximately 2.7 V (see
