数据： 700-mW Mono Low-Voltage Audio Power Amplifier with Differential Inputs 数据表
TPA751是一款桥接负载（BTL）音频功率放大器，专为需要内置扬声器的低压应用而开发。 TPA751采用3.3V电源供电，可为BTL 8提供250mW的连续功率 - 
在整个语音频段频率下，负载小于0.6％THD + N.虽然该器件的特性为20 kHz，但其操作已针对窄带应用（如无线通信）进行了优化。在大多数应用中，BTL配置无需在输出端使用外部耦合电容，这对于小型电池供电设备尤为重要。该器件具有关断功耗模式的关断模式，关断期间电源电流为1.5 nA。 TPA751采用3.0×3.0 mm MicroStar Junior？ （BGA），8引脚SOIC表面贴装封装和表面贴装PowerPAD ?? MSOP。
PowerPAD和MicroStar Junior是德州仪器公司的商标。
