说明
AW87319 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, 2 nd Smart K audio amplifiers. AW87319 integrates the high-voltage synchronous Boost with efficiency up to 84% as the Class D power stage supply. It significantly improves the output dynamic range of music. AW87319 integrates Awinic’s proprietary Triple-Level Triple-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87319 noise floor is as low as to 47uV, with 102dB 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. AW87319 supports speaker and receiver 2-in-1 applications. In the receiver application, Class D power stage voltage is straightly supplied by battery. AW87319 controls internal registers through the I 2C interface. Register parameters include Boost Output Voltage, Boost maximum input peak current, Class D gain, Triple-Level Triple-Rate AGC parameters. AW87319 built-in over current protection, over-temperature protection and short circuit protection function, effectively protect the chip. AW87319 uses small 2.76mm*2.36mm CSP-19 package.
