+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.
