FEATURE - HT8313 GENERAL DESCRIPTION - Anti-Clipping Function (ACF) - Adaptive Charge Pump Regulator HT8313 is a Class D audio amplifier which can deliver continuous 5.5W output power into a 4Ω speaker with 5V power supply when THD+N = 10%. - Maximum Voltage Gain: 28d B The class D audio amplifier’s power supply is - Output Power (Class D) adaptively boosted by the integrated charge pump regulator which only works while the output power 5.5W (VBAT=5V, RL=4Ω, THD+N=10%) is big enough. This will significantly extend the 4.5W (VBAT=5V, RL=4Ω, THD+N=1%) - Output Power (Class AB) 2.8W (VBAT=5V, RL=4Ω, THD+N=10%) 2.3W (VBAT=5V, RL=4Ω, THD+N=1%) 技 k - Power Supply -Input VBAT：2.7V to 5.5V e -Output PVDD：6.6V - Quiescent Current: 3m A 科 T - Shutdown Current: <1u A - Class AB / Class D selectable e - Filter-less Modulation, Eliminating Output Filter 特 c - Over Current Protection, Thermal Protection, Low voltage malfunction prevention function r included - Pb-Free Packages , SOP10L-PP 源 u - HT8313 APPLICATIONS o - Smart Speakers - Wireless Speakers - Portable Audio Devices - Smart Phones 矽 S - HT8313 TYPICAL APPLICATION playing time in battery supply applications. HT8313 features Anti-Clipping Function (ACF) which detects output signal clip due to the over input signal and suppresses the output signal clip automatically. Also, it can adapt the output clip...
