说明

AW87317A is specifically designed to enhance overall sound quality. It is an upgrading 7th-generation class K audio amplifier with high efficiency, low noise, ultra-low distortion and capability of outputting constant large volume.
With integrated AWINIC proprietary NCN output AGC audio algorithm, AW87317A can eliminate noise in playback and improve sound quality and effect. Using a novel K-Charge pump technology, its integrated charge pump efficiency can reach 93%, and power amplifier’s overall efficiency can reach 80%. With high efficiency, AW87317A can greatly prolong smart phone usage time.
AW87317A noise floor is as low as to 53μV, with 97dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.008% brings high-quality musical enjoyment.
AW87317A has a setting of 4-step selectable speaker-guard output power level from 0.6W to 1.2W, suitable for different rated power speakers. Within lithium battery voltage range, it keeps output power constant, preventing voice from degrading.
AW87317A supports speaker and receiver two-in-one application. The Class D Receiver Mode has an ultra-low output noise of 22μV. Under this mode, the power of PA is supplied by VBAT.
AW87317A has built-in over-current protection, over-temperature protection and short-circuit protection. AW87317A is available in a FCQFN 1.60mm X 1.60mm X 0.55mm-16L.
