ADC DIGITAL FILTER CHARACTERISTICS

Notes:

Response is clock-dependent and will scale with Fs. Note that the response plots (Figures 27 to 30 on

page 70) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.

HPF parameters are for Fs = 48 kHz.

Characteristics are based on the default setting in register “HPF Control (Address 09h)” on page 47.

10. Settling time decreases at higher corner frequency settings.
