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 5: These specifications apply for VS=±15V and 0˚C≤TA≤+70˚C. VOS, IBand IOS are measured at VCM=0. Note 6: The input bias currents are junction leakage currents which approximately double for every 10˚C increase in the junction temperature, Tj . 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, PD. Tj =TA+θjA PD where θjA is the thermal resistance from junction to ambient. Use of a heat sink is recommended if input bias current is to be kept to a minimum. Note 7: Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice. VS = ±6V to ±15V.
