The TDA7297 stereo amplifier board uses DC 8-18V power supply (12V recommended), with an effective output power of 15Wx2, making it ideal for upgrading and modifying low-power desktop speakers. Many speaker systems use amplifier boards around 5W, which can make your speakers sound weak and unpleasant. This amplifier board uses the original imported TDA7297 dual-channel amplifier chip from the renowned European company SGS-THOMSON. It is designed for DC power supply and can be directly powered by a 12V battery. The voltage range is 9-15V, with 12V recommended. The output power reaches 15W+15W, and the peak power reaches 30W+30W. It provides a DIY entertainment platform for electronics enthusiasts; even those without electronics knowledge can easily set it up.
Advantages of this board: No current surge noise upon startup, high fidelity with no static noise! The sound quality is superb—the treble is delicate, smooth, and transparent, without any noticeable harshness; the bass is solid, full, powerful, and well-controlled.
If using a switching power adapter or other variable power supply, low-frequency noise may occur due to poor linearity. This amplifier's circuit design is reasonable and has undergone rigorous testing before being released to the market. There is no annoying start-up sound, no static noise, and the sound is so quiet you can only hear your breathing—it's truly fantastic!
This compact 12V power supply amplifier board truly lives up to its reputation as a superb amplifier module. Technicians used this board to drive two dual 3-inch 50W speakers with equally excellent sound quality, without any sense of strain.
