Monolithic Voltage Reference Output Thermal Drift Sensitivity
Monolithic reference thermal drift sensitivity combines silicon junction non-linearities, piezoresistive mechanical package stress, and solder reflow hysteresis.
Endpoint Method
Measurement Boundary
A mathematical calibration protocol that establishes a sensor transfer function by measuring the response at only the start and finish of the operating range. In linear transducer calibration, the endpoint method creates a reference line through the two terminal measurements.
Accuracy Boundary
Linearity measurements based on this reference line do not account for mid-range structural errors or thermal curves. The resulting linearity value is often less tight than one derived using a best-fit straight-line technique. Since it represents the absolute worst-case deviation at any single intermediate point, the endpoint method offers a conservative metric that is highly trusted by industrial system integrators.
Production Implementation
In factory test benches, this technique allows for very rapid sensor screening. Test engineers apply the minimum and maximum rated pressures or displacements, and then immediately calculate the slope. Utilizing the endpoint method avoids the time-consuming process of stepping through a dozen intermediate levels, significantly reducing the duration of the manufacturing cycle without compromising the validation of the basic operating limits.
Verification Standard
Calibration certificates explicitly state which methodology was used to derive the accuracy specification. If a sensor is certified via the endpoint method, the buyer can expect higher real-world precision when operating near the limits of the scale. This predictability makes it popular for hydraulic and pneumatic controls where the safety thresholds are set close to the extreme ends of travel.
