说明
AW8738 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, eighth generation class K audio amplifiers. AW8738 integrated Awinic proprietary multi-level AGC audio algorithm, effectively eliminate music noise, improve sound quality and volume. Using a new generation 93% efficiency K-Chargepump, power amplifier’s overall efficiency reaches 83%, greatly prolong the mobile phone usage time. AW8738 noise floor is as low as to 40uV, with 99.6dB high signal-to-noise-ratio(SNR). The ultra-low distortion 0.008% and unique multi-level AGC technology brings high quality music enjoyment.
AW8738 has 0.6W, 0.8W, 1W and 1.2W four selectable speaker-guard output power levels, which is suitable for different rated power speakers, greatly improve the volume, effectively protect speakers. With multi-level AGC audio algorithms, the music is pure natural and melodious. AW8738 is compatible with AW8736, AW8737, output power cannot drop along with lithium battery voltage lower down. Within lithium battery voltage range(3.3V-4.35V), output power is constant.
The AW8738 uses Awinic proprietary TDD-Noise suppression technology and EMI suppression technology, effectively restrain TDD-Noise and EMI interference.
AW8738 built-in over current protection, over-temperature protection and short circuit protection function, effectively protect the chip. The AW8736 uses small 2mmx2mm FC-16 package.
