比起普通晶体管的音质是好很多，但如果与起集成块功放管相比，集成块功放的制作容易，外围元件少，条件没场效应管功放的苛刻，大功率场效应管的型号很多不胜枚举，可以根据电路的实际参数要求进行选择。

音质音色的怎样，不完全由器件决定，还与电路形式及电路的性能有很大的关系。不管用什么器件，如果都能达到理想的标准，那么听觉上就分辨不出来了

TDA7850
Quad BTL output with HSD/offset detection, stand-by and mute inputs
TDA7850供应商：拍明芯城
The TDA7850 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/NChannel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.
The TDA7850 integrates a DC offset detector.
Key Features
