net SM6801A Class-D Mono Ampliﬁer for Portable Device OVERVIEW The SM6801A is an analog-input, class-D mono ampliﬁer.
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 equalizer pin for output speaker frequency characteristics adjustment.
These 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 dynamic speaker.
The device is available in miniature 16-pin QFN packages, and requires only a peripheral chip ca...
