The SM7513 is a stereo audio power amplifier that drives 3 W/channel of continuous RMS power into a 3-Ω load. Advanced up/down volume control minimizes external components and allows BTL (speaker) volume control and SE (earphone) volume control. Wireless headphone benefit from the integrated feature set that minimizes external components without sacrificing functionality.


To simplify design, the speaker volume level is adjusted by applying a up/down gain control to the up/down terminals.
