DAC interface

1) In one of our design we used DAC3283irgzt, below figure show the configuration how we used in our design,

2) Same DAC we are planning use in new design here we need to send the baseband, for this we need to remove the transformer.

below is the schematic for that, let me know if any modification required in this

Hi Prashanth,

Can you send the schematic file as an attachment? The resistor values at the output are hard to read.

Note that, the most important consideration is the output compliance voltage of the DAC is not exceeded. For maximum output swing at 20mA full scale current, the output common mode should be biased to 3.3V and the effective impedance should be 100ohms (differential) or 50ohms (single ended).

Thanks,

Eben.
