AW87318 is specifically designed to enhance overall sound quality. It is an upgrading 8th-generation class K audio amplifier with high efficiency, low noise, ultra-low distortion and capability of outputting constant large volume.
With integrated AWINIC proprietary Multi-Level AGC audio algorithm, AW87318 can eliminate noise in playback and improve sound quality and effect. Using a novel K-Chargepump technology, its integrated charge pump efficiency can reach 93%, and power amplifier’s overall efficiency can reach 83%. With high efficiency, AW87318 can greatly prolong smart phone usage time.
AW87318 noise floor is as low as to 43μV, with 98.8dB high signal-to-noise-ratio (SNR). The ultra-low distortion 0.008% brings high-quality musical enjoyment.
AW87318 has a setting of 7-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.
AW87318 supports speaker and receiver two-in-one application. The Class D Receiver Mode has an ultra-low output noise of 19μV. Under this mode, the power of PA is supplied by VBAT.
AW87318 has built-in over-current protection, over-temperature protection and short-circuit protection. AW87318 is available in a 1.60mm×1.60mm, 0.4mm pitch FCQFN-16 package.
