说明

AW87327 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, AW87327 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 80%. With high efficiency, AW87327 can greatly prolong smart phone usage time.
AW87327 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.
AW87327 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.
AW87327 supports speaker and receiver two-in-one application. The Class AB Receiver Mode has an ultra-low output noise of 11μV and an ultra-high power supply noise suppression of -100dB@217Hz.
AW87327 has built-in over-current protection, over-temperature protection and short-circuit protection. AW87327 is available in a 1.575mm×1.575mm, 0.4mm pitch CSP-14 package.
