5V、差分输入、DirectDrive、130mW立体声耳机放大器，带有关断

MAX9722A/MAX9722B立体声耳机放大器是针对那些电路板空间很有限的便携设备而设计的。MAX9722A/MAX9722B采用独特的DirectDrive®结构，在单电源供电下能产生以地为参考的输出，从而省去了大容量隔直电容，节省了成本、电路板空间以及元件高度。此外，放大器的增益也由内部设定(-2V/V、MAX9722B)，或外部调整(MAX9722A)。MAX9722A/MAX9722B每个通道可向16Ω负载输出70mW，或向32Ω负载输出130mW，THD+N仅为0.009%。217Hz时80dB的电源抑制比(PSRR)使该器件可以在没有附加线性调节器的情况下，在嘈杂的数字 • 工作在2.4V至5.5V的单电源下\n• 无需大容量隔直电容\n• 不会因为输出电容而使低频响应变差\n• 可调增益(MAX9722A)或固定增益-2V/V (MAX9722B)\n• THD+N仅0.009%\n• 低静态电流(5.5mA)\n• 放大器输出端具有±8kV ESD保护(人体模型)\n• 采用节省空间的16引脚薄型QFN (3mm x 3mm x 0.8mm)封装;
