TDA7498E 2.0 High Power Digital Power Amplifier Board

1. TDA7498E Chip: TDA7498E is a dual channel digital audio power amplifier IC with high efficiency and high fidelity, which is widely used in audio equipment. This chip has the advantages of low distortion, high output power, and low power supply voltage, making it suitable for power amplification applications in audio systems. 2. Support BTL Mode: Short circuit of J1, J2, J3, J4 on the back of the power amplifier board) 36V power supply, 3 ohms mono 220W output (TDA7498, TDA7498L chips do not support this function 3. Temperature Control Fan: The fan uses a temperature control scheme that is energy-saving, environmentally friendly, and low noise. The industrial grade temperature control fan has low noise and good heat dissipation effect, providing protection for high-power heat dissipation (the temperature of the heat sink is high enough for the fan to operate and force heat dissipation) 4. Fever Capacitor: Symmetric capacitor design, 12 fever capacitors, 470uf x 12=5640uf. High quality inductor, inductor with low heat generation and high sound quality. 5. Heat dissipation method:temperature controlled forced air cooling (when the temperature of the heat sink reaches a certain level and the fan is running for forced heat dissipation) Power amplifier chip:TDA7498E 2X160W chip Output power:2x160W(using a 4 ohm impedance horn unit, input voltage 36V DC, output power 160W+160W) Channel:Dual channel stereo Frequency response:20Hz-20KHz Horn impedance:4 ohms, 6 ohms, 8 ohms Working voltage:12-36V DC with input polarity reverse protection (The actual power of the speaker is large enough, and the recommended voltage is 24V, with a DC voltage of 8A or above. If the power supply is too small, it cause distortion and sound interruption, which cannot produce a shocking effect.) Protection function:Short circuit, overheat power supply anti reverse connection Size:About 120x78mm/4.72x3.07inch Weight:165g
