GENERAL DESCRIPTION
The SM7513 is a stereo audio power amplifier that drives 3 W/channel of continuous RMS power into a 3-Ωload. 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.
