AW8737AQNR 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, AW8737AQNR can eliminate noise in playback and improve sound quality and effect. Using a novel Smart K-Chargepump technology, its integrated charge pump efficiency can reach 93%, and power amplifier’s overall efficiency can reach 81%. With high efficiency, AW8737AQNR can greatly prolong smart phone usage time.
AW8737AQNR noise floor is as low as to 53μV, with 97dB high signal-to-noise-ratio (SNR).
AW8737AQNR 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 AW8737AQNR uses Awinic proprietary TDD-Noise suppression technology and EMI suppression technology, effectively restrain TDD-Noise and EMI interference.
AW8737AQNR has built-in over-current protection, over-temperature protection and short-circuit protection. AW8737AQNR is available in a 1.60mm×1.60mm, 0.4mm pitch WBQFN-16 package.
