ANT8908 is a Class G audio power amplifier with high integration, built-in high efficiency boost, high signal-to-noise ratio, low floor noise and ALC (anti-crack) function. The booster power supply side supports 10-level current limit adjustment. The current limit value can be adjusted by real-time software during the working period of the power amplifier to prevent excessive discharge of the battery. When the lithium battery is powered at 3.7V, the drive single channel 2Ω load can output 10.5W constant power.
    The ALC function can automatically detect the output distortion and dynamically adjust the amplifier gain, which can avoid the output clipping distortion caused by the excessive amplitude of the input signal such as music, or the battery voltage fluctuation, significantly improve the music quality and improve the listening sensation.
    Class AB operating mode ensures no interference in applications with radio functions. Class AB/D switching function and IC enable pin reuse, the application is very flexible.
    In addition, ANT8908 built-in overcurrent protection, overheat protection functions to ensure the reliability and stability of the chip in various application environments.
