Description

AW87318 is specifically designed to eliminate smart mobile phone music noise, to enhance overall sound quality, which is a new high efficiency, low noise, ultra-low distortion, constant large volume, upgrading eighth generation class K audio amplifiers. AW87318 integrated Awinic proprietary Multi-Level AGC audio algorithm, effectively eliminate music noise, improve sound quality and volume. Using a new generation K-Chargepump technology, efficiency reaches 93%, power amplifier’s overall efficiency reaches 83%, greatly prolong the mobile phone usage time. AW87318 noise floor is as low as to 43uV, with 98.8dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.008% and unique Multi-Level AGC technology brings high quality music enjoyment. AW87318 has 0.6W, 0.7W, 0.8W, 0.9W, 1W, 1.1W and 1.2W seven subdivision selectable speaker-guard output power levels, which is suitable for different rated power speakers. With multi-level AGC audio algorithms, the music is pure natural and melodious. Within lithium battery voltage range (3.3V--4.35V), output power is constant, preventing voice becomes smaller and smaller during usage of cell phone. AW87318 supports speaker and receiver two-in-one application. In receiver mode, the output noise is as low as to 19uV, amplifier is in class D mode, powered by VBAT. AW87318 has built-in over current protection, over-temperature protection and short circuit protection function, effectively protect the chip. AW87318 uses small 0.4mm pitch 1.6mmx1.68mm CSP-14 package.
