interference (EMI) that drives speakers directly without an external filter.
It has automatic short-circuit recovery protection and a wide operating voltage range from 2.5V to 5.5V,
especially suitable for 8Ω loads. At a supply voltage of 5.0V,
especially suitable for 8Ω loads. At a supply voltage of 5.0V,
The SGM2822 is capable of delivering up to 1.7W of output power for 8Ω loads
while keeping total harmonic distortion plus noise (THD+N) below 10%.
while keeping total harmonic distortion plus noise (THD+N) below 10%.
The SGM2822 is distinguished by its 88% high efficiency and a power supply rejection ratio (PSRR) of 70dB at 217Hz.
This makes it ideal for battery-powered high-fidelity audio applications.
Compared to traditional Class D audio power amplifiers,
the SGM2822 is outstanding in reducing electromagnetic interference radiation.
