With the same supply voltage, the BTL signal output range is 2 times of Half-bridge amplifier due to the load with differential drive.
同时，在相同的电源电压下，BTL输出信号摆幅是半桥式放大器的2倍，因为负载是差分驱动的。

It uses tow-stage differential amplifiuers to increasee the circuit gain and uses a source follower as a voltage buffer to decrease signal volt- age losing.
该电路应用两级差动放大增加电路增益，利用源极跟随器作为电压缓冲器以减少信号电平损失。
