## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Decoupling
- Pitfall : Inadequate decoupling causing oscillation and noise
- Solution : Implement 100nF ceramic + 10μF tantalum capacitors within 5mm of supply pins
Thermal Management
- Pitfall : Junction temperature exceeding 150°C in high-ambient environments
- Solution : Use thermal vias under exposed pad and ensure minimum 2cm² copper pour
Input Protection
- Pitfall : ESD damage during handling and overvoltage transients
- Solution : Series resistors (100Ω) with TVS diodes on all input lines
### Compatibility Issues with Other Components
Digital Interface Compatibility
- Issue : 3.3V logic level mismatch with 5V microcontrollers
- Resolution : Use level translators or select 3.3V-compatible host processors
Sensor Interface Considerations
- Issue : High-impedance sensor loading affecting accuracy
- Resolution : Buffer high-impedance sources or use guard rings
Clock Synchronization
- Issue : Clock jitter with certain crystal oscillators
- Resolution : Select oscillators with <50ps period jitter specification
### PCB Layout Recommendations
Power Distribution
- Use star-point grounding with separate analog and digital grounds
- Implement power planes for VDD and VSS with minimum 2oz copper weight
Signal Routing
- Route differential pairs with controlled impedance (100Ω differential)
- Keep analog traces >5mm from digital and switching signals
- Use guard rings around high-impedance input nodes
Thermal Design
- Utilize all 9 thermal vias under exposed pad (0.3mm diameter recommended)
- Connect thermal pad to analog ground plane for heat dissipation
- Ensure minimum 4mm² copper area for heat sinking
