## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Improper Decoupling
- Issue : Inadequate decoupling leads to oscillations and reduced performance
- Solution : Use 100nF ceramic capacitor placed within 5mm of power pins, plus 10μF bulk capacitor
Pitfall 2: Thermal Management
- Issue : Overheating in high-ambient temperature applications
- Solution : Implement proper thermal vias, consider heatsinking, and monitor junction temperature
Pitfall 3: Input Protection
- Issue : Damage from ESD or overvoltage conditions
- Solution : Incorporate TVS diodes and current-limiting resistors at inputs
Pitfall 4: Grounding Issues
- Issue : Ground loops and noise coupling degrade signal integrity
- Solution : Implement star grounding and separate analog/digital ground planes
### Compatibility Issues with Other Components
ADC Interface Considerations:
- Ensure proper impedance matching with successive approximation ADCs
- May require additional buffering for sigma-delta converters
- Watch for settling time requirements with high-speed converters
Power Supply Compatibility:
- Compatible with switching regulators but requires additional filtering
- Works well with LDO regulators for noise-sensitive applications
- Ensure power supply sequencing avoids latch-up conditions
Sensor Interface Compatibility:
- Excellent compatibility with bridge sensors and RTDs
- May require external protection with piezoelectric sensors
- Consider input bias current with high-impedance sources
### PCB Layout Recommendations
Power Distribution:
- Use separate power planes for analog and digital sections
- Implement multiple vias for power connections to reduce inductance
- Route power traces with adequate width (minimum 20 mil for 1A current)
Signal Routing:
- Keep input traces short and away from noisy digital signals
- Use guard rings around high-impedance inputs
- Maintain symmetrical layout for differential signal paths
