Hello, O'Mellin,

MICBIAS, HPROUT, HPRCOM, HPLOUT, HPLCOM and RIGHT_LOM pins can be left floated.

MIC1LP/M and MIC2LP/M should be routed to a 0.47uF capacitor to GND since these pins are DC-biased.

Best regards,
Luis Fernando Rodríguez S.

for future reference, where can this information be found ? do you recommend to power down the associated block, if the function is not used?

thanks

Hello, O'Mellin,

This information is not on the datasheet. We will update it in the next version.

Regarding the associated block, you are right. If the function is not used, it is recommended to power down the associated block.
