Wiring Guide (Basic Setup)
Power Supply
- Use a regulated 12V DC supply (7–15V range)
- Ensure at least 2A current capacity for full output
Speaker Output
- Connect 8Ω speakers to LOUTP/LOUTN and ROUTP/ROUTN
- Do not ground speaker terminals—BTL outputs are floating
Audio Input
- Use a preamp or DAC with differential output
- For single-ended sources (e.g., 3.5mm jack), use resistive summing or transformer isolation
Shutdown/Mute
- Pull SHDN pin low to mute or shut down
- Leave floating or pull high for normal operation
Integration Tips for Embedded Systems
- Add low-pass filters on inputs for noise suppression
- Mount on a heat-dissipating surface if driving full power continuously
- Ideal for pairing with Bluetooth audio modules, MP3 decoders, or microcontroller-based UI
Troubleshooting
| Issue | Possible Cause | Fix |
|---|---|---|
| No sound | SHDN pin low or input miswired | Pull SHDN high, check inputs |
| Distorted output | Overdriven input or low supply voltage | Reduce input level, check VCC |
| Speaker hum/noise | Ground loop or poor filtering | Use isolated inputs, add filters |
| Module overheating | Continuous high-power output | Improve airflow or heatsinking |
