  12 description:
  13   The MAX98388 is a mono Class-D speaker amplifier with I/V feedback.
  14   The device provides a PCM interface for audio data and a standard
  15   I2C interface for control data communication.

  47       For cases where a single combined channel for the I/V feedback data
  48       is not sufficient, the device can also be configured to share
  49       a single data output channel on alternating frames.
  50       In this configuration, the current and voltage data will be frame
  51       interleaved on a single output channel.
