TPA6205A1 1.25-W Mono Fully Differential Audio
Power Amplifier
With 1.8-V Input logic Thresholds 数据表 
TPA6205A1器件是一款1.25 W单声道全差动放大器，设计用于驱动阻抗至少为8Ω且扬声器功耗小于37 mm2的扬声器（ZQV）封装选项）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1.7 mA。 TPA6205A1采用节省空间的2 mm×2 mm MicroStar Junior BGA封装，节省空间的3 mm×3 mm QFN（DRB）封装。
85-dB等特性PSRR从90 Hz到5 kHz，提高了RF整流抗扰度，并且PCB面积小，使TPA6205A1成为无线手机的理想选择。 TPA6205A1具有4s的快速启动时间和最小的弹出功能，是PDA应用的理想选择。
