+title: Awinic AW8738 Audio Amplifier
+
+maintainers:
+ - Stephan Gerhold <stephan@gerhold.net>
+
+description:
+ The Awinic AW8738 is a simple audio amplifier with different operation modes
+ (set using one-wire pulse control). The mode configures the speaker-guard
+ function (primarily the power limit for the amplifier).
