Products Description
TDA7297 amplifier board with wiring terminals 2.0 Dual channel 15W+15W
Volume: 50 x 50 x 42mm ( excluding potentiometer handle), ultra small size suitable for any space.
Voltage: DC 9-15V, recommended DC voltage 12V, current above 2A
Power: 15W+15W
Output impedance: 4-8 ohms
Net weight: 44g
Advantages of this board: No current surge sound during startup, high fidelity and no static noise! The sound quality is super good - the high notes are delicate, soft, transparent, and have no obvious jarring sound; The bass is sturdy, full, powerful, and allows for easy retraction and release. Recently, a small number of customers have reported that there is some noise on this board, mostly due to unresolved power supply issues. After testing, there is no noise at all when powered by a 12V2A or above battery or a 12V30W or above transformer. If powered by a switching power supply or other variable power supply, poor linearity may result in low noise.
The core of this amplifier board is the original imported TDA7297 dual channel amplifier chip, produced by the famous European company SGS THOMSON Microelectronics. The power supply is designed for direct current power supply, which can be directly powered by a 2 volt battery. The voltage range is 9-15V, with a recommended voltage of 12V. The output power can reach up to 15W+15W, and the peak power can reach 30W+30W. The volume is small but the sound is super shocking, suitable for any occasion
This amplifier board is designed according to official standard circuits. The PCB circuit board uses high-quality FR4 fiberglass board with a thickness of 16mm, which has reasonable wiring and compact component layout. No current surge sound during startup, 100% no static noise. The parameters of TDA7297 can be viewed on the official ST website: detailed dimension diagram:
