Absolute Maximum Ratings
1
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.
7.
Max Self Heating =
ΘJA x (VDD x IDD). Assumes a capacitive load.
