DAC COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
(cont) (Note 12)
Notes: 8. Slow Roll-Off interpolation filter is only available in control port mode.
9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 21 to 44) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
10. Single and Double Speed Mode Measurement Bandwidth is from stopband to 3 Fs.
Quad Speed Mode Measurement Bandwidth is from stopband to 1.34 Fs.
11. De-emphasis is available only in Single Speed Mode; Only 44.1 kHz De-emphasis is available in Stand-
Alone Mode.
12. Plots of this data are contained in the “Appendix” on page 47. See Figure 21 through Figure 44.
