Specifications over temperature range are assured by design. (2) Power-supply rejection is encompassed in the accuracy specification. (3) Temperature sensitivity is the average slope to the equation VO = (–11.77 × T) + 1.860V. (4) VOUT is calculated from temperature with the following equation: VO = (–3.88 × 10 –6 × T2) + (–1.15 × 10–2 × T) + 1.8639V, where T is in °C. (5) Nonlinearity is the deviation of the calculated output voltage from the best fit straight line. (6) The TMP20 transfer function requires the output voltage to rise above the 1.8V supply as the temperature decreases below +15°C. When operating at a 1.8V supply, it is normal for the TMP20 output to approach 1.8V and remain at that voltage as the temperature continues to decrease below +15°C. This condition does not damage the device. Once the temperature rises above +15°C, the output voltage resumes changing as the temperature changes, according to the transfer function specified in this document. For more information about the transfer function, see the Transfer Function section. Copyright © 2009, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Link(s): TMP20 |
