#163152 - Temperature accuracy Responding to: ???'s previous message |
From the data sheet for the TMP03
TYP MAX
Temperature Error TA = 25°C 1.0 3.0 °C
–25°C < TA < +100°C1 1.5 4.0 °C
–40°C < TA < –25°C1 2.0 5.0 °C
Temperature Linearity 0.5 °C
Long-Term Stability 1000 Hours at 125°C 0.5 °C
...so the accuracy is pretty appalling. I'd go with Satish's suggestion - use a thermistor and a look up table or whatever. Steve |
