## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Power Supply Decoupling
- Problem: Noise and instability in output signals
- Solution: Implement 100nF ceramic capacitor close to power pins and 10μF tantalum capacitor within 2cm
Pitfall 2: Improper Grounding
- Problem: Ground loops causing measurement errors
- Solution: Use star grounding topology and separate analog/digital grounds
Pitfall 3: Thermal Management Issues
- Problem: Performance degradation at elevated temperatures
- Solution: Provide adequate copper pour for heat dissipation and maintain ambient temperature below 85°C
Pitfall 4: Input Protection Omission
- Problem: Component damage from transient voltages
- Solution: Implement TVS diodes and series resistors on sensitive inputs
### Compatibility Issues with Other Components
Digital Interfaces:
- Compatible with standard CMOS/TTL logic levels
- Requires level shifting when interfacing with 1.8V systems
- I²C/SPI compatibility through external interface ICs
Analog Components:
- Optimal performance with low-noise op-amps (e.g., OPA series)
- Avoid pairing with switching regulators in close proximity
- Recommended ADC pairing: 16-bit or higher resolution converters
Power Supply Requirements:
- LDO regulators preferred over switching regulators
- Minimum power supply rejection: 60dB at 100Hz
- Supply sequencing not critical but recommended
### PCB Layout Recommendations
Component Placement:
- Place decoupling capacitors within 3mm of power pins
- Keep sensitive analog components away from digital noise sources
- Maintain minimum 2mm clearance from board edges
Routing Guidelines:
- Power traces: Minimum 20mil width for main supply lines
- Signal traces: Use 45° angles instead of 90° bends
- Ground plane: Continuous ground plane on adjacent layer
- D
