(1) 100% production tested at TA = 25°C. 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) + 1.860 V.
(4) VOUT is calculated from temperature with the following equation:
VO = (–3.88 × 10–6 × T2) + (–1.15 × 10–2 × T) + 1.8639 V,
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 1.8-V supply as the temperature decreases below 15°C. When operating at a 1.8-V supply, it is normal for the TMP20 output to approach 1.8 V 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.
