13 APPLICATION INFORMATION
The application information as given in Fig.9 is an optimum application environment. Simplification is possible at the cost
of some performance degradation. The following notes apply:
The capacitors at the output of the DAC can be reduced. It should be noted that the cut-off frequency of the DC filter
also changes.
The capacitors at the input of the ADC can also be reduced. It should be noted that the cut-off frequency of the
capacitor with the 12 kW input resistance of the ADC will also change.
