Tool/software:

Hi E2E team,

Assuming our application is relatively simple, the block diagram is as follows:
Some of the pins of this chip will not be used. Does it have special hardware settings? I saw relevant instructions in the document. Maybe I didn't look carefully. Please guide me to find it, thanks.

For example: (just floating is fine?)

HPLOUT

HPLCOM

HPROUT

MICBIAS

MIC3R

    Hi Caspar,

    Outputs (HPLOUT, HPCOM, HPROUT, MICBIAS) can be left floating. Unused inputs (MIC3R and MIC3L) should be AC coupled to GND with a 0.47uF or similarly sized capacitor.

    Best regards,
