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.

* Advanced DC Volume Control With 2-dB Steps

From -40 dB to 20 dB

* Depop circuitry

* Low quiescent current

* 1uA shutdown current

* 3W into 3Ω from 5.5V supply

* Thermal protection

* Compact configuration and minimum external

components
