offset. External resistance tolerance and temperature coefficient not included in this spec.

5. Thermometer error (expressed in °C) is the difference between [V

(T) - 395]/6.20 and the DS56 case

temperature at V

= 3.0V, thus taking into account sensor error, DC offset error, sensor amplifier

gain variations, and amplifier nonlinearity.
