AW8737A 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, AW8737A 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, AW8737A can greatly prolong smart phone usage time.
AW8737A 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.
AW8737A 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.
The AW8737A uses Awinic proprietary TDD-Noise suppression technology and EMI suppression technology, effectively restrain TDD-Noise and EMI interference.
AW8737A has built-in over-current protection, over-temperature protection and short-circuit protection. AW8737A is available in a FCQFN 1.60mmX1.60mmX 0.55mm-16L.
