AW87569 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, 5th generation Smart K audio amplifier. AW87569 integrates AWINIC’s proprietary Triple-Level Triple-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87569 integrates high voltage synchronous adaptive Boost with efficiency up to 88% as the class D power stage supply, significantly improving the dynamic range of music. AW87569 noise floor is as low as to 45μV at speaker mode, with 104dB high signal-to-noise ratio (SNR). The ultra-low distortion 0.015% and unique Triple-Level Triple-Rate AGC technology bring high quality music enjoyment. It supports speaker and receiver 2-in-1 application. Quiescent current is 6.8mA when VDD is equal to 3.6V. In the receiver mode, its ultra-low noise is 11μV. Class D receiver also has high PSRR performance to completely suppress TDD-noise. It 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. It built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87569 features FCQFN 2.0mm X3.0mm X 0.55mm-20L package.
