COMBINED DAC INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
Notes:
12. Response is clock dependent and will scale with Fs. Note that the response plots (Figure 38 to Figure 41
on page 82) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
13. Measurement Bandwidth is from Stopband to 3 Fs.
