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, boost-

ing 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 capacitor to form a miniature ampliﬁer circuit.
