Darf ich annehmen, dass ich mit dem ADC/der Soundkarte auch DC messen kann, wenn ich "HPFE High Pass Filter Enable Pin" abschalte, sodass

Zitat: 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 HPFE pin. 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”.

Wäre interessant für ein Power-Meter mit Low-Side Messung.
