AW87390 is specifically designed to improve the musical outputdynamic range, enhance the overall sound quality, which is a newhigh efficiency, low noise, constant large volume, 6th Smart Kaudio amplifier. AW87390 integrates awinic's proprietaryTriple-Level Triple-Rate AGC audio algorithm, effectivelyeliminating music noise and improving sound quality andvolume. AW87390 integrated efficiency up to 90% of AdaptiveDO-Chargepump technology, significantly improving the dynamic rangeof the music output and power consumption of audio system. AW87390 noise floor is as low as to 38μV at speaker mode, with102dB high signal-to-noise-ratio (SNR). The ultra-lowdistortion 0.008% and unique Triple-Level Triple-Rate AGCtechnology bring high quality music enjoyment. AW87390 supportspeaker and high power receiver stereo applications; supportsspeaker and receiver 2-in-1 applications, class AB/D receiveroptional, ultra-low noise is9.5μV. AW87390 controls internalregisters through the 12C interface. Register parametersinclude output voltage, power amplifier gain, Triple-LevelTriple-Rate AGC parameters etc.AW87390 built-in over currentprotection, over temperature protection and short circuitprotection function, effectively protect the chip. AW87390features small FCQFN2.0mmX2.5mmX0.55mm-16L package.
