5 / 10 page 5 NOTES 1. Maximum errors over all ranges are guaranteed based on the known behavior characteristic of the AD590. 2. For one-trim accuracy specifications, the 205oC span is assumed to be trimmed at 25oC; for all other spans, it is assumed that the device is trimmed at the midpoint. 3. For the 205oC span, it is assumed that the two-trim temperatures are in the vicinity of 0oC and 140oC; for all other spans, the specified trims are at the endpoints. 4. In precision applications, the actual errors encountered are usually dependent upon sources of error which are often overlooked in error budgets. These typically include: a. Trim error in the calibration technique used b. Repeatability error c. Long term drift errors Trim Error is usually the largest error source. This error arises from such causes as poor thermal coupling between the device to be calibrated and the reference sensor; refer- ence sensor errors; lack of adequate time for the device being calibrated to settle to the final temperature; radically different thermal resistances between the case and the sur- roundings (RθCA) when trimming and when applying the device. Repeatability Errors arise from a strain hysteresis of the package. The magnitude of this error is solely a function of the magnitude of the temperature span over which the device is used. For example, thermal shocks between 0oC and 100oC involve extremely low hysteresis and result in repeatability errors of less than ±0.05oC. When the thermal- shock excursion is widened to -55oC to 150oC, the device will typIcally exhibit a repeatability error of ±0.05oC (±0.10 guaranteed maximum). Long Term Drift Errors are related to the average operat- ing temperature and the magnitude of the thermal-shocks experienced by the device. Extended use of the AD590 at temperatures above 100oC typically results in long-term drift of ±0.03oC per month; the guaranteed maximum is ±0.10oC per month. Continuous operation at temperatures below 100oC induces no measurable drifts in the device. Besides the effects of operating temperature, the severity of thermal shocks incurred will also affect absolute stability. For thermal-shock excursions less than 100oC, the drift is diffi- cult to measure (<0.03oC). However, for 200oC excursions, the device may drift by as much as ±0.10oC after twenty such shocks. If severe, quick shocks are necessary in the application of the device, realistic simulated life tests are rec- ommended for a thorough evaluation of the error introduced J Grade Maximum Errors (oC) NUMBER OF TRIMS TEMPERATURE SPAN (oC) LOWEST TEMPERATURE IN SPAN (×oC) -55 -25 0 255075 100 125 None 10 4.2 4.6 5.0 5.4 5.8 6.2 6.6 7.2 None 25 5.0 5.2 5.5 5.9 6.0 6.9 7.5 8.0 None 50 6.5 6.5 6.4 6.9 7.3 8.2 9.0 - None 100 7.7 8.0 8.3 8.7 9.4 - - - None 150 9.2 9.5 9.6 ----- None 205 10.0 ------- One 10 0.3 0.2 0.2 0.2 0.2 0.2 0.2 0.3 One 25 0.9 0.6 0.5 0.5 0.5 0.6 0.8 0.9 One 50 1.9 1.5 1.0 1.0 1.0 1.5 1.9 - One 100 2.3 2.2 2.0 2.0 2.3 - - - One 150 2.5 2.4 2.5 ----- One 205 3.0 ------- Two 10 0.1 (Note 10) (Note 10) (Note 10) (Note 10) (Note 10) (Note 10) 0.1 Two 25 0.2 0.1 (Note 10) (Note 10) (Note 10) (Note 10) 0.1 0.2 Two 50 0.4 0.2 0.1 (Note 10) (Note 10) 0.1 0.2 (Note 10) Two 100 0.7 0.5 0.3 0.7 1.0 - - - Two 150 1.0 0.7 1.2 ----- Two 205 1.6 ------- NOTE: 10.
