AW8737FCR数据手册Awinic中文资料规格书

描述 Description

AW8737 is completely compatible with AW8736， isdesigned to enhance smart mobile phone sound quality,which is a new high efficiency, low noise, ultra-lowdistortion, constant large volume, seventh generationclass K audio amplifiers. Using a new generationK-Chargepump technology, efficiency reaches 93%,power amplifier's overall efficiency is up to 80%, greatlyprolong the mobile phone usage time. The AW8737noise floor is as low as to 52μV, with 97.3dB highsignal-to-noise-ratio(SNR).  The  ultra-low  distortion0.008% and unique no-crack-noise (NCN) technologybrings high quality music enjoyment.AW8737 has 0.8 W, 1 W and 1.2 W three selectablespeaker-guard output power levels, recommended usingrated power of 0.7W and above speakers, whichgreatly improve the volume, and effectively protectspeakers. AW8737 integrated unique NCN technology,the output power cannot drop along with lithium batteryvoltage lower down. Within lithium battery voltage range(3.3V--4.35V), output power is constant, preventing thevoice becomes smaller and smaller during usage of cellphone.The AW8737 uses awinic proprietary TDD-Noisesuppression  technology  and  EMI  suppressiontechnology, effectively restrain TDD-Noise and EMIinterference.
