NOTES:
1. All voltages are referenced to ground, unless otherwise specified.
2. Solder according to IPC standards.
3. Specified for V

sourcing 1.0 µA (max) and V
REF
load current = 50 µA.
4. Includes error associated with internal temperature sensor, bandgap voltage V
REF
, and comparator
offset. External resistance tolerance and temperature coefficient not included in this spec.
5. Thermometer error (expressed in °C) is the difference between [V
O
(T) - 395]/6.20 and the DS56 case
temperature at V
DD
= 3.0V, thus taking into account sensor error, DC offset error, sensor amplifier
gain variations, and amplifier nonlinearity.
