描述 Description

AW87390 is specifically designed to improve the musical output dynamic range, enhance the overall sound quality, which is a new high efficiency, low noise, constant large volume, 6th Smart K audio amplifier. AW87390 integrates awinic’s proprietary Triple-Level Triple-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87390 integrated efficiency up to 90% of Adaptive DO-Chargepump technology, significantly improving the dynamic range of the music output and power consumption of audio system. AW87390 noise floor is as low as to 38μV at speaker mode, with 102dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.008% and unique Triple-Level Triple-Rate AGC technology bring high quality music enjoyment.AW87390 support speaker and high power receiver stereo applications；supports speaker and receiver 2-in-1 applications，class AB/D receiver optional，ultra-low noise is 9.5μV.AW87390 controls internal registers through the I2C interface. Register parameters include output voltage, power amplifier gain, Triple-Level Triple-Rate AGC parameters etc.AW87390 built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87390 features small FCQFN 2.0mmX2.5mmX0.55mm-16L package.
