AW87359FCR

High Efficiency Low Noise Large Volume Handsets Stereo TLTR-AGC 3rd Smart K Audio Amplifier

AW87359 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, 3rd Smart K audio amplifier. AW87359integrates awinic’s proprietary Triple-Level Triple-Rate AGC audio algorithm, effectively eliminating music noise and improving sound quality and volume. AW87359 integrated efficiency up to 90% of high voltage DO-Chargepump technology, significantly improving the dynamic range of themusic output.

 AW87359 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 musicenjoyment.AW87359 support speaker and high power receiver stereo applications;supports speaker and receiver 2-in-1applications,class AB/D receiver optional,ultra-low noise is11μV.AW87359 controls internal registers through the I2Cinterface. Register parameters include output voltage, power amplifier gain, Triple-Level Triple-Rate AGC parameters etc.

AW87359 built-in over current protection, over temperature protection and short circuit protection function, effectively protect the chip.
