Description

AW87392E 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. AW87392E integrates awinic’s proprietary Multi-Level AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87392E integrated efficiency up to 95.4% of Adaptive DO-Charge pump technology, significantly improving the dynamic range of the music output and power consumption of audio system. AW87392E noise floor is as low as to 20μV at speaker mode, with 105dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.03% and unique Multi-Level AGC technology bring high quality music enjoyment. AW87392E controls internal registers through the I2C interface. Register parameters include output voltage, power amplifier gain, Multi-Level AGC parameters etc. AW87392E built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip. AW87392E features small FCQFN 2.5mmX2.0mmX0.55mm-16L package.
