描述 Description

AW87339 is specifically designed to improve the musical output dynamic range, enhance the overall sound quality. It is a new high efficiency, low noise, constant large volume, 3rd generation Smart K audio amplifier. AW87339 integrates AWINIC’s proprietary Triple-Level Triple-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87339 integrated high voltage DO-Chargepump technology with efficiency up to 90%, significantly improving the dynamic range of the music output. AW87339 noise floor is as low as to 38μV at speaker mode, with 102dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.02% and unique Triple-Level Triple-Rate AGC technology bring high quality music enjoyment.
AW87339 supports speaker and high power receiver stereo applications, supports speaker and receiver 2-in-1 applications, class AB/D receiver optional, ultra-low noise is 9μV.
AW87339 controls internal registers through the I2C interface. Register parameters include chargepump output voltage, power amplifier gain, Triple-Level Triple-Rate AGC parameters, etc.
AW87339 built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87339 features small 2.545mm*2.075mm CSP-18 package.
