Analog Output and Filtering
The application note “Design Notes for a 2-Pole Filter with Differential Input” discusses the second-order
Butterworth filter and differential to single-ended converter which was implemented on the CS4365 evalua-
tion board, CDB4365, as seen in
tion for an external filter. Therefore, the DAC system phase and amplitude response will be dependent on
the external analog circuitry. The off-chip filter has been designed to attenuate the typical full-scale output
level to below 2 Vrms.
Figure 19
shows how the full-scale differential analog output level specification is derived.
