NOTES:

1. All voltages are referenced to ground, unless otherwise specified.

2. Solder according to IPC standards.

3. Specified for VTEMP sourcing 1.0 µA (max) and VREF load current = 50 µA.

4. Includes error associated with internal temperature sensor, bandgap voltage VREF, and comparator

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

5. Thermometer error (expressed in °C) is the difference between [VO(T) - 395]/6.20 and the DS56 case

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

gain variations, and amplifier nonlinearity.
