July 2005 - 70A04006
Notes:
1. Absolute maximum ratings are limits beyond
which operation may cause permanent damage to
the device. These are stress ratings only;
functional operations at or above these limits is
not implied.
2. Human Body Model: 100pF capacitor discharged
through a 1.5k
Ω
resistor into each pin. Machine
Model: 200pF capacitor discharged directly into
each pin.
3. These specifications are guaranteed only for the
test conditions listed.

Notes:
4. Accuracy (expressed in °C) = Difference between calculated output voltage and measured output voltage.
Calculated output voltage = 10mV/°C multiplied by device’s case temperature at specified conditions of temperature,
voltage and power supply with an offset of 500mV (see Fig. 1).
5. Non-linearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight
line, over the device’s rated temperature range.
6. Lowest output current should be targeted; higher currents result in more self-heating of the device.
