Class-D operation provides high efﬁciency and low power consumption.

The device also incorporates an original real-time operation dynamic range compression function that effectively suppresses the distortion in the saturation level region output by soft-clipping, boosting the average sound pressure from the speaker during playback.

It also incorporates an input

SM6801A Features

* make the device ideal for use in mobile telephones and speaker applications requiring miniaturization and high-efﬁciency. The output stage has a BTL output conﬁguration where the output waveform inverts only the modulation components, enabling direct drive connection, without using an LC ﬁlter, to a
