DC12-36V 2*100W Digital Amplifier Audio Board TDA7498 Power Class D Amplifier
Features:
1. Gain Adjustment: 4 levels of gain, flexible and optional (25.6dB, 31.6dB, 35.1dB, 37.6dB).
2. Heat Sink: Super-large aluminium alloy heat sink, beautiful, with fast heat dissipation, safe and reliable for long-term work.
3. Chip Inductors: High-quality inductors can accurately screen signals while isolating interference.
4. Multifunctional Potentiometer: It can control the power switch and volume adjustment, sealed design, sensitive and durable.
5. Electrolytic Capacitor: Symmetrical capacitor design, eight major fever capacitors 330μF*8=2640μF.
Specifications:
Item Name: High-power Dual Channel Power Amplifier Board
Chip model: TDA7498
Supply Voltage: DC 12-36V
Output Power: 100W x 2 max
Sound Channel: dual channel 2.0 output
Output Impedance: 4-8 ohm
Frequency: 20HZ-20KHz
Size: About 83 * 64 * 26mm
Weight: about 105g
Output Power: 100W+100W (VCC=36V RL=6Ω THD=10%)
Output Power: 80W+80W (VCC=34V RL=8Ω THD=10%)
Note:
1. The power supply must use a DC power supply and have a large enough current.
2. The output power depends on the power supply voltage, current and speaker impedance.
3. If using a 4 ohm speaker, it is recommended that the voltage should not exceed 26V to avoid loss.
Package include:
1 x Audio Amplifier Board
