6. Guaranteed by design. See Figure 2. RL and CL reflect the recommended minimum resistance and
maximum capacitance required for the internal op-amp’s stability. CL affects the dominant pole of the
internal output amp; increasing CL beyond 100 pF can cause the internal op-amp to become unstable.
DAC COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
7. Filter response is guaranteed by design.
8. For Single-Speed Mode, the Measurement Bandwidth is 0.5465 Fs to 3 Fs.
For Double-Speed Mode, the Measurement Bandwidth is 0.577 Fs to 1.4 Fs.
For Quad-Speed Mode, the Measurement Bandwidth is 0.7 Fs to 1 Fs.
9. De-emphasis is available only in Single-Speed Mode.
10. Response is clock dependent and will scale with Fs. Note that the amplitude vs. frequency plots of this
data (Figures 18 to 27) have been normalized to Fs and can be de-normalized by multiplying the X-axis
scale by Fs.
