TPA6211A1 3.1-W Mono Fully Differential Audio
Power Amplifier 数据表 
TPA6211A1是一款3.1W单声道全差动放大器，设计用于驱动至少3Ω阻抗的扬声器，同时仅消耗20 mm 2 大多数应用中的总印刷电路板（PCB）面积。该器件工作电压为2.5 V至5.5 V，静态电源电流仅为4 mA。 TPA6211A1采用节省空间的3 mm×3 mm SON（DRB）和8引脚MSOP-PowerPAD（DGN）封装。
具有-80 dB电源电压抑制功能Hz至2 kHz，改善了RF整流抗扰度，小巧的PCB面积，以及最小的弹出速度，使TPA6211A1成为PDA和智能手机应用的理想选择。
