DESCRIPTION
AW8736 is designed to enhance smart mobile phone
sound quality,which is a new high efficiency, ultra-low
distortion, constant large volume, sixth generation class
K audio amplifiers. Using a new generation of charge
pump technology：K -Chargepump structure, efficiency
as high as 92%, power amplifier’s overall efficiency
reaches 75%, greatly prolong the mobile phone usage
time. 0.02% ultra-low distortion and unique
no-crack-noise (NCN) technology brings high quality
music enjoyment.
AW8736 integrated K-Chargepump booster circuit,
the output power cannot drop along with lithium battery
voltage lower down. Within lithium battery voltage
range(3.3 V - 4.35V), output power is constant, providing
high quality music enjoyment. AW8736 has 0.8 W, 1 W
and 1.2 W three output power level, recommended using
rated power of 0.7W and above speakers, which
greatly improve the volume, and effectively protect
speakers.
The AW8736 uses awinic proprietary TDD-Noise
suppression technology and EMI suppression
technology, effectively restrain TDD-Noise and EMI
interference.
AW8736 built-in over current protection,
over-temperature protection and short circuit protection
function, effectively protect the chip. The AW8736 uses
small 2mmx2mm FC-16 package.
