说明

AW87568A is a high efficiency, low noise, low power consumption, constant large volume Smart K audio amplifier. AW87568A integrates AWINIC’s proprietary Multi-Level Multi-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87568A integrates high voltage adaptive Boost with efficiency up to 91% , it greatly improves efficiency at small signal, Overall efficiency up to 88.5% when output power is 0.5W. AW87568A noise floor is as low as to 31μV at speaker mode, with 103dB high signal-to-noise ratio (SNR). AW87568A has super volume receiver mode, it can deliver 550mW output power into an 8Ω speaker at 8.5μV noise. AW87568A supports speaker and receiver 2-in-1 application. Quiescent current is 4.6mA when VDD is equal to 3.6V. In the receiver mode, its ultra-low noise is 8.5μV. Class D receiver also has high PSRR performance to completely suppress TDD-noise. AW87568A built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87568A is available in a FCQFN 2.0mm X3.0mm X 0.55mm-20L package.
