* Static-sensitive device. Unused devices must be stored in conductive

material. Protect devices from static discharge and static fields. Stresses

above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. These are stress ratings only and functional

operation of the device at these or any other conditions above those

indicated in the operational sections of the specifications is not implied.

Exposure to Absolute Maximum Rating Conditions for extended periods

may affect device reliability.

temperature driving a 100pF capacitive load.

4. Accuracy = Difference between calculated output voltage (10mV/

°C x Device case temperature at specified temperature and power

supply) and measured output voltage expressed in

°C.

5. Nonlinearity = deviation of output voltage versus temperature from the best-fit straight line over the device rated temperature range.
