The recommended output filter configuration is shown in Figure 14. This filter configuration accounts for the normally
differing AC loads on the AOUT+ and AOUT- differential output pins. It also shows an AC coupling configuration
which minimizes the number of required AC coupling capacitors.
The CS4271 does not include phase or amplitude compensation for an external filter, and therefore the DAC system
phase and amplitude response will be dependent on the external analog circuitry. Figure 15 shows the full-scale an-
alog output levels.
