单通道AB类音频功放

ETK4871是一颗带关断模式的音频功放IC。在5V输入电压下工作时，负载（3Ω）上的平均功率为3W，且失真度不超过10％。而对于手提设备而言，当VDD作用于关断端时，ETK4871将会进入关断模式，此时的功耗极低，IQ仅为0.6A。\r\n\r\n　　ETK4871是专为大功率、高保真的应用场合所设计的音频功放IC。所需外围元件少且在2.0V～5.5V的输入电压下即可工作。 • 无需输出耦合电容或外部缓冲电路\r\n• 稳定的增益输出\r\n• 外部增益设置\r\n• 封装形式：SOP8(ETK4871M)、SOP8-PP (ETK4871MR)、DIP8(ETK4871P)、MSOP8(ETK4871U)\r\n• 注：ETK4871采用带散热片的SOP8封装形式，在封装形式中以SOP8–PP来区分，命名则在原来的规则上，再后缀字母R。;

OUTPUT RAIL TO RAIL 1W AUDIO POWER AMPLIFIER WITH STANDBY MODE

DESCRIPTION The TS4871 is an Audio Power Amplifier capable of delivering 1W of continuous RMS Output Power into 8Ω load @ 5V. This Audio Amplifier is exhibiting 0.1 distortion level (THD) from a 5V supply for a Pout = 250mW RMS. An external standby mode control reduces the supply current to less
