## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Decoupling
- Pitfall : Inadequate decoupling causing performance degradation
- Solution : Implement multi-stage decoupling with 100 nF ceramic capacitors at each power pin and 10 μF tantalum capacitors per power rail
Thermal Management
- Pitfall : Overheating in high-ambient temperature environments
- Solution : Provide adequate copper pour for heat dissipation and consider forced air cooling for continuous full-load operation
Signal Integrity
- Pitfall : Signal degradation due to improper grounding
- Solution : Use separate analog and digital ground planes with single-point connection near the device
### Compatibility Issues
Digital Interface Compatibility
