COMBINED DAC INTERPOLATION AND ONCHIP ANALOG FILTER RESPONSE
12. Response is clock dependent and scales with Fs. Note that the response plots (Figures 30 and 33 on
page 78) 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.
