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.

description:
For cases where a single combined channel for the I/V feedback 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.
