GENERAL DESCRIPTION
FEATURES
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.
* Advanced DC Volume Control With 2-dB Steps
From -40 dB to 20 dB
* Depop circuitry
* Low quiescent current
* 1uA shutdown current
