AW87394 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, Smart K audio amplifier. AW87394 integrates awinic’s proprietary Multi-Level AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87394 integrated efficiency up to 92% of Adaptive DO-Charge pump technology, significantly improving the dynamic range of the music output and power consumption of audio system. AW87394 noise floor is as low as to 28μV at speaker mode, with 102dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.02% and unique Multi-Level AGC technology bring high quality music enjoyment. AW87394 controls internal registers through the I2C interface. Register parameters include output voltage, power amplifier gain, Multi-Level AGC parameters etc. AW87394 built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87394 features small FCQFN 2.5mmX2.0mmX0.55mm-15L package.
