Mechanical Stress

Mechanical stress or vibration can impact the stability of the internal wire bonds of the ADC, causing calibration drift. When under physical stress, the temperature characteristics of the ADC or package can behave in unexpected ways, thus a frequent calibration is recommended. Additionally, mechanical stresses on front-end components can alter electrical characteristics, resulting in degradation of the matching network. As a result, any physical shocks, stresses, or vibrations can require a re-calibration before the ADC performance resumes as expected.
