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 operation 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.

Notes:
3. These specifications are guaranteed only for the test conditions listed.
4. Accuracy (expressed in °C) = Difference between calculated output voltage and measured output voltage. Calculated output
voltage = -11.77mV/°C multiplied by device’s case temperature at specified conditions of temperature, voltage and power
supply plus an offset of 1863.9 mV at 0°C.
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. High capacitive loads may be driven by the output in a static mode, but it may require a delay time before initial read at power
up to allow for the RC time constant of the charging capacitor.
