„ Digital High Pass Filter

The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 1.0Hz (@fs=48kHz)

and scales with sampling rate (fs).

HPF is controlled by CKS2-0 pins (Table 2). If HPF setting (ON/OFF) is changed at operating, click noise occurs by

changing DC offset. It is recommended that HPF setting is changed at PDN pin = “L”.
