描述 Description

8.5V High Efficiency High PSRR Low Noise Large Volume 2-in-1 TLTR-AGC 3rd Generation Smart K Audio AmplifierW87519 is specifically designed to improve the musicaloutput dynamic range, enhance the overall sound quality. Itis a new high efficiency, high PSRR，low noise, constantlarge volume, 3rd generation Smart K audio amplifier.AW87519 integrates AWINIC’s proprietary Triple-LevelTriple-Rate AGC audio algorithm, effectively eliminatingmusic noise and improving sound quality and volume.AW87519 integrates high voltage synchronous Boost withefficiency 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-lowdistortion 0.04% and unique Triple-Level Triple-Rate AGCtechnology 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 Dreceiver also has high PSRR performance to completelysuppress TDD-noise.AW87519 controls internal registers through the I2Cinterface. Register parameters include boost output voltage,boost maximum input peak current, PA gain, Triple-LevelTriple-Rate AGC parameters, etc.AW87519 built-in over current protection, over temperatureprotection and short circuit protection function, effectivelyprotect the chip.?
