I am trying to buffer an DAC through FDAs.
The output of FDA will be connected with a modulator.
One end of the modulator is connected with ground.
So the reason for me to buffer the DAC is to avoid the ground loop. The DAC is a single ended DAC. If it is connected with modulator directly, a ground loop will be formed.
Therefore, the DAC will be connected with FDAs to create a differential output.
1. In this application, bandwidth is not required (5kHz) is sufficient, but precision is highly required. (0.1mV output)
2. The output will be -10V --- +10V
Do you think it is necessary to make the output differential?
If so, any suggestions on high precision FDA? Bandwidth is not a problem.
Thank you very much.
