## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Decoupling
- Pitfall : Inadequate decoupling causing oscillation and noise issues
- Solution : Implement 100nF ceramic capacitor close to VDD pin and 10μF tantalum capacitor within 2cm
Thermal Management
- Pitfall : Overheating in high-ambient temperature applications
- Solution : Ensure adequate copper pour for heat dissipation and consider forced air cooling above 85°C
Signal Integrity
- Pitfall : Ground bounce affecting precision measurements
- Solution : Use separate analog and digital ground planes with single-point connection
### Compatibility Issues
Digital Interface Compatibility
- I²C Communication : Requires pull-up resistors (2.2kΩ typical) for proper operation
- SPI Interface : Compatible with 3.3V logic levels; level shifting needed for 5V systems
- Clock Synchronization : Maximum clock frequency of 10MHz; overshooting causes timing violations
Analog Signal Chain Integration
- ADC Compatibility : Direct interface with 12-16 bit successive approximation ADCs
- Sensor Interfaces : Optimized for bridge sensors and thermocouple inputs
- Reference Voltage : Requires external 2.5V reference for optimal performance
### PCB Layout Recommendations
Component Placement
