Objective data sheet
10.13.1 Basic output configuration
10.13 Output configuration
The use of a differentially-coupled transformer output provides optimum distortion
performance (see
helps to match the impedance and provides electrical isolation.
The DAC1408D650 can operate up to 2 V
is recommended to connect the center tap of the transformer to a 62
to the 3.3 V analog power supply, in order to adjust the DC common mode to
approximately 2.7 V (see
