+title: Analog Devices MAX98388 Speaker Amplifier
+
+maintainers:
+ - Ryan Lee <ryans.lee@analog.com>
+
+description:
+ The MAX98388 is a mono Class-D speaker amplifier with I/V feedback.
+ The device provides a PCM interface for audio data and a standard
+ I2C interface for control data communication.

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

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