+
+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.

+ In this configuration, the current and voltage data will be frame
+ interleaved on a single output channel.
