The APA2615 is a stereo, high efficiency, Class-D audio
amplifier available in a QFN5.2x6.2-32 package.
The filter-free Class-D architecture eliminates the exter-
nal low pass filters, and save the PCB space and BOM
costs. The APA2615 also has a spread clock function that
reduces the high frequency radiation and low the EMI
noise. The Zero-crossing-change function changes the
gain when both output (V and V ) crossing together

OUTN
can minimum the pop noise. The power limit function can
protect the speaker when output signal excess the
speaker limit rating. The non-clip and DRC functions are
eliminate the distortion at large input signal, and can fit
the high dynamic input signal to a small dynamic speaker.
The operating voltage is from 8V to 16.5V. The APA2615
is capable of driving 10W at 12V or 18W at 16V into 8Ω
speaker and provides thermal and over-current
protections. It also can detect the DC that prevents the
speaker voice coil from being destroyed.
