AW87317CSR

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

AW87317 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 AW87317 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. AW87317 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. AW87317 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. AW87317 supports speaker and receiver two-in-one application. In receiver mode, the output noise is as low as to 22uV, amplifier is in class D mode, powered by VBAT.
