Such amplifiers are primarily interfaced with SoundWire but they also support analog mode which is configurable by setting one of the pins to high/low. In such case the WSA881X amplifier is configurable only using i2c. To have stereo two WSA881X amplifiers are required but mono configurations are also possible.
