Note 2:
For operating at elevated temperatures, the device must be derated based on a thermal resistance of 115C/W typ junction to ambient for the N package,
and 158C/W typ junction to ambient for the H package.
Note 3:
Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
Note 4:
The power dissipation limit, however, cannot be exceeded.

Note 6:
The input bias currents are junction leakage currents which approximately double for every 10C increase in the junction temperature, T
j
. Due to the limited
production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the ambient
temperature as a result of internal power dissipation, P

recommended if input bias current is to be kept to a minimum.
