CS4922
7 DAC FILTER RESPONSE PLOTS
Figures 20 through 23 show the overall frequency
response, passband ripple and transition band for
the CS4922 DACs. Figure 23 shows the DACs’ de-
viation from linear phase. Fs is the selected sample
frequency. Since the sample frequency is program-
mable, the filters will adjust to the selected sample
frequency. Fs is also the FSYNC frequency.
