ANT8816 is a low-EMI, low-noise, anti-distortion, single-channel AB/D-class dual-mode audio amplifier with built-in boost. When powered by a 3.7V lithium battery, it can output 8W power when driving a 3Ω load. The ALC anti-distortion function can automatically detect output distortion, dynamically adjust the amplifier gain, and ensure that the output audio signal does not have large distortion. The battery discharge current can be controlled to prevent the battery from being instantly pulled down, affecting system stability. ANT8816 also has AB class working mode, and does not bring any interference in applications with radio function.
