Runic Operational Amplifier Selection Guide
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
- ✗ Selecting op-amp based only on bandwidth
- ✗ Ignoring offset drift in precision applications
- ✗ Not checking stability with capacitive loads
- ✗ Overlooking power consumption in battery apps
Frequently Asked Questions
1. When should I use zero-drift op-amps?
Use zero-drift op-amps when: (1) High gain (>50x) is required - offset gets amplified; (2) Precision DC measurements - need stable offset over time/temp; (3) Low-frequency signals (<10Hz) - 1/f noise is significant; (4) Calibration is expensive - zero-drift reduces need for calibration. Don't use zero-drift when: (1) Fast settling is critical - auto-zero takes time; (2) Very high bandwidth needed (>10MHz); (3) Cost is primary concern - general-purpose op-amps are cheaper.
