AW87519 is specifically designed to improve the musical output dynamic range, enhance the overall sound quality. It is a new high efficiency, high PSRR,low noise, constant large volume, 3rd generation Smart K audio amplifier. AW87519 integrates AWINIC’s proprietary Triple-Level Triple-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87519 integrates high voltage synchronous Boost with efficiency up to 88% as the class D power stage supply, significantly improving the dynamic range of music. AW87519 noise floor is as low as to 43μV at speaker mode, with 103dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.04% and unique Triple-Level Triple-Rate AGC technology bring high quality music enjoyment. AW87519 supports speaker and receiver 2-in-1 application. In the receiver mode, its ultra-low noise is 18μV. Class D receiver also has high PSRR performance to completely suppress TDD-noise. AW87519 controls internal registers through the I2C interface. Register parameters include boost output voltage, boost maximum input peak current, PA gain, Triple-Level Triple-Rate AGC parameters, etc. AW87519 built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87519 features small FCQFN 2.0mmX3.0mmX0.55mm-20L package.
