Hifi STA508 Digital Power Amplifier Board 2* 80W Tone board Class D DC18-24V

Description:

STA508 10-35V single power supply 80W*2 or 160W*1 PWM signal input class D power amplifier, built-in mute, STBY; no sound on and off, built-in short circuit, overheating, overload, overcurrent, protection circuit, meet the smaller Radiator environment. PO=80W*2 (Vcc=35V THD=10% f=1khz RL=8 ohms).
Electrolytic capacitor adopts 220UF/50V electrolysis to ensure strong and continuous power support.
The resistance selects 0805 0603 high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
Very small size and high power. No noise, the circuit design is very reasonable, without any low noise.
