description:

  The MAX98396 is a mono Class-DG speaker amplifier with I/V sense.

  The device provides a PCM interface for audio data and a standard

  I2C interface for control data communication.

  The MAX98397 is a variant of MAX98396 with wide input supply range.

  adi,interleave-mode:

    description:

      For cases where a single combined channel for the I/V sense data

      is not sufficient, the device can also be configured to share

      a single data output channel on alternating frames.

      In this configuration, the current and voltage data will be frame

      interleaved on a single output channel.
