High Power Class D Digital Power Amplifier Power amplifier chip: original TDA7498E (TDA7498L is 2X80W chip, TDA7498 is 2X100W chip, TDA7498E is 2X160W chip) Output power: 2X160W (using 4 ohm impedance speaker unit, input voltage 36V DC, output power 160W + 160W)
Working voltage: 15~ 24VDCdirect currentWith input polarity to reverse protection (the real power of the speaker is large enough, the recommended voltage is 24V, DC power above 8A, and the power supply power is too small, which will distort and break the sound, etc.)
Speaker impedance: 4 ohms 6 ohms 8 ohms
Heat dissipation method: temperature control forced air cooling (the temperature of the heat sink is high to a certain extent, and the fan operation forces heat dissipation)
Work efficiency: 85% (official data)
Support BTL mode (J1, J2, J3, J4 short connection on the back of the power amplifier board) 36V power supply 3 ohm mono 220W output (TDA7498, TDA7498L chip does not support this function)
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
