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
On board 0.35 A high side driver
Low external component count:Internally fixed gain (26 dB)No external compensationNo bootstrap capacitors
Protections:Output short circuit to gnd, to Vs, across the loadVery inductive loadsOverrating chip temperature with soft thermal limiterOutput DC offset detectionLoad dump voltageFortuitous open gndReversed batteryESD
Mute function
ST-BY function
High output power capability:4 x 50 W/4 Ω max.4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %4 x 80 W/2 Ω max.4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %
Excellent 2 Ω driving capability
MOSFET output power stage
Low output noise
Automute at min. supply voltage detection
Hi-Fi class distortion
