DESCRIPTION
AW87329 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 generation Smart K audio amplifiers.
AW87329 integrates Awinic’s proprietary Triple-Level
Triple-Rate AGC audio algorithm, effectively eliminating
music noise and improving sound quality and volume.
AW87329 integrated efficiency up to 90% of High voltage
DO-Chargepump technology, significantly improving the
dynamic range of the music output. AW87329 noise floor
is as low as to 38μV, 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.
AW87329 supports speaker and receiver 2-in-1
applications, AB/D Receiver optional, ultra-low noise is
9uV.
AW87329 controls internal registers through the I
2
C
interface. Register parameters include charge pump
output voltage, power amplifier gain, Triple-Level
Triple-Rate AGC parameters, etc.
AW87329 built-in over current protection, over
temperature protection and short circuit protection
function, effectively protect the chip. AW87329 features
small 2.58mm*2.11mm CSP-18 package.
