AW8737SCSR

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

AW8737S is designed to enhance smart mobile phone sound quality, which is a new high efficiency, low noise, ultra-low distortion, constant large volume, upgrading seventh generation class K audio amplifier. 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 AW8737S noise floor is as low as to 53μV, with 97dB high signal-to-noise-ratio(SNR). The ultra-low distortion 0.008% and unique no-crack-noise (NCN) technology brings high quality music enjoyment. AW8737S has 0.6W, 0.8W, 1W and 1.2W four selectable speaker-guard output power levels, recommended using rated power of 0.5W and above speakers. AW8737S 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 AW8737S uses Awinic proprietary TDD-Noise suppression  technology  and  EMI  suppression technology, effectively restrain TDD-Noise and EMI interference.
