DESCRIPTION
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. AW87359
integrates 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 the
music 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 music
enjoyment.
AW87359 support speaker and high power receiver
stereo applications；supports speaker and receiver 2-in-1
applications，class AB/D receiver optional，ultra-low noise is
11μV.
AW87359 controls internal registers through the I
2
C
interface. 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. AW87359 features small FCQFN
2.5mmX2.0mmX0.55mm-16L package.
