Audio Amplifier Module 2x 15w Dual channel Stereo12v DC DIY Kit Power TDA7297
This DIY kit includes all the essential components for building a 15W+15W stereo power amplifier using the TDA7297 integrated circuit. It’s an ideal choice for electronics hobbyists who enjoy assembling and experimenting with audio amplifiers.
Package Includes:
- 1 × TDA7297 IC (without heatsink)
- 1 × Printed Circuit Board (PCB)
- Passive components (resistors, capacitors, diodes)
Recommended Additional Components:
- Power capacitor: 2200µF to 10000µF
- Heatsink (recommended size: 100×30×45mm)
- Volume control potentiometer (if not using preamp)
Specifications:
- Load Resistance: 4–10 Ω
- Supply Voltage: 9–20V DC (Recommended: 12V 4A)
- Input Signal: Stereo linear (0–0.5V)
- Output Power: 15W + 15W (up to 30W + 30W peak)
- Board Dimensions (assembled): 34×29×25mm
- Efficiency: Up to 90%
- Net Weight: 10–15g

Important Notes:
- This is a DIY kit, not a finished product. Assembly and basic soldering skills are required.
- If you hear noise from the board:
- Ensure a clean power supply (avoid noisy commercial adapters).
- Use a potentiometer to control the input signal. If not used, connect two 47K resistors to each audio input.
- If using mains-powered rectifier, upgrade 100µF filter capacitor to ≥1000µF.
- If the IC overheats, add an appropriate heatsink.
Performance Highlights:
- No startup "pop" noise
- High signal-to-noise ratio
- Clear, transparent treble and strong, full bass
- Capable of driving two 6.5" 100W speakers with impressive clarity
