PCB Layout Guidelines for Runic Analog Circuits
This technical reference document provides detailed information about runic product specifications, characteristics, and performance parameters. Use this information to support your design and analysis activities.
Electrical characteristics are specified over the operating temperature range unless otherwise noted. Parameters are guaranteed by design, testing, or statistical analysis. Typical values is the most likely parametric norm at 25°C.
Thermal characteristics require careful attention during system design. The junction-to-ambient thermal resistance depends on the mounting configuration, PCB copper area, and airflow conditions. Use thermal simulation tools to predict operating temperatures under actual conditions.
Reliability data is based on accelerated life testing and field failure analysis. Mean time between failures (MTBF) calculations follow industry-standard methodologies. Contact BeiLuo for detailed reliability reports and qualification data.

⚠️ Common Pitfalls
- ✗ Routing ground as traces instead of using plane
- ✗ Placing decoupling caps too far from ICs
- ✗ Not guarding high-impedance nodes
- ✗ Ignoring thermocouple voltage errors
Frequently Asked Questions
1. How do I minimize ground noise in mixed-signal designs?
Minimizing ground noise: (1) Use separate analog and digital ground planes; (2) Connect at single point near power entry; (3) Route high-speed digital signals over digital ground; (4) Keep analog signals away from digital switching; (5) Use ferrite beads to isolate analog supplies. The key principle is to prevent digital return currents from flowing through analog ground paths. Never route digital traces over analog ground plane - the return currents will couple into your analog circuits.
