Notes:
11. Response is clock-dependent and will scale with Fs. Note that the response plots (Figures 41 to Note 44
on page 90) have been normalized to Fs and can be denormalized by multiplying the X-axis scale by Fs.
HPF parameters are for Fs = 48 kHz.
12. Characteristics are based on the default setting in register “HPF Control (Address 1Bh)” on page 75.
13. Settling time decreases at higher corner frequency settings.
