Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Signal distortion or inaccuracy
Cause: Component degradation (e.g., aging resistors, capacitor drift) or thermal stress affecting reference voltage stability and linearity
Complete output failure or erratic behavior
Cause: Power supply issues (e.g., voltage spikes, brownouts), electrostatic discharge (ESD) damage to semiconductor components, or solder joint fatigue from thermal cycling
Maintenance Indicators
