AW8737FCR

High efficiency 、Low noise 、Ultralow distortion 、Constant large volume 、Seventh generation Class K Audio Amplifier

AW8737 is completely compatible with AW8736, is designed to enhance smart mobile phone sound quality, which is a new high efficiency, low noise, ultra-low distortion, constant large volume, seventh generation class K audio amplifiers. Using a new generation K-Chargepump technology, efficiency reaches 93%, power amplifier’s overall efficiency is up to 80%, greatly prolong the mobile phone usage time. The AW8737 noise floor is as low as to 52μV, with 97.3dB high signal-to-noise-ratio(SNR).  The  ultra-low  distortion 0.008% and unique no-crack-noise (NCN) technology brings high quality music enjoyment. AW8737 has 0.8 W, 1 W and 1.2 W three selectable speaker-guard output power levels, recommended using rated power of 0.7W and above speakers, which greatly improve the volume, and effectively protect speakers. AW8737 integrated unique NCN technology, the output power cannot drop along with lithium battery voltage lower down. Within lithium battery voltage range (3.3V--4.35V), output power is constant, preventing the voice becomes smaller and smaller during usage of cell phone. The AW8737 uses awinic proprietary TDD-Noise suppression  technology  and  EMI  suppression technology, effectively restrain TDD-Noise and EMI interference.
